Jakub Kiwior's Aerial Win Rate Reshapes Poland's 2026 Defensive Plan

Poland conceded seven goals from set pieces during the 2022 World Cup, the most of any team in the tournament. Against Argentina alone, they lost 62% of aerial duels. The retirement of Kamil Glik at age 32 left a gap in central defense that, at the time, seemed impossible to fill. Two years later, Jakub Kiwior has emerged as a potential solution, armed with aerial duel data that suggests Poland's defensive approach may look fundamentally different in 2026.

Poland's Set-Piece Vulnerability Exposed in 2022

During the group stage, Poland's set-piece defending was erratic. Against Saudi Arabia, they conceded from a corner after a routine delivery found an unmarked striker. Against Argentina, the same pattern repeated: a short corner led to a header that forced a desperate save, and the rebound was turned in. In the round of 16, France exploited Poland's inability to clear first-contact headers, with Giroud scoring from a set-piece move.

Data from the tournament shows Poland ranked 28th out of 32 teams in aerial duel success rate at 47%. Only Senegal and South Korea were worse among teams that reached the knockout stage. The absence of a dominant center-back who could consistently win first-contact headers was the single biggest structural issue.

Kamil Glik, at 34, had been that player for nearly a decade. His retirement after Euro 2024 left a void that Jan Bednarek and Kamil Piątkowski could not fully fill. Bednarek, while positionally sound, wins only 58% of his aerial duels at club level—a figure that drops further when facing elite target men. Piątkowski, still developing, lacks the physical presence to dominate in the air.

What made the 2022 failure particularly frustrating was that Kiwior, then 22, was on the bench for key moments. He had played only 12 minutes in the group stage, all against Mexico, and was not used against Argentina or France. His club form at Spezia had shown promise, but the coaching staff hesitated to trust a young defender in high-stakes knockout matches.

Kiwior's 2024-25 Aerial Data Suggests a Shift

By the 2024-25 season, Kiwior had established himself as one of the most effective aerial defenders in Europe. At Arsenal, his aerial duel win rate reached 72.4% across all competitions, according to Opta data as of November 2024. That figure places him among the top five center-backs in the Premier League, ahead of Virgil van Dijk's 68% and roughly level with Ruben Dias.

The numbers are not a fluke. During the 2023-24 season at Arsenal, Kiwior averaged 4.1 aerial wins per 90 minutes, a rate that led all Arsenal defenders and ranked third in the Premier League among center-backs with at least 1,000 minutes. He also led Serie A in headed clearances during the 2022-23 season while on loan at Spezia, with 3.8 per game.

What makes these stats relevant for Poland is the context. Kiwior is not merely winning headers inside his own box; he is winning them in the middle third, cutting out long balls before they become dangerous. Against West Ham in October 2024, he made four headed clearances outside the penalty area, each one snuffing out a counter-attack before it developed.

Some analysts caution that Premier League aerial duel statistics can be inflated by the style of play—more long balls from opponents who press high. But Kiwior's numbers in Serie A, a more tactical league, were similarly strong. His 2023-24 Serie A aerial win rate of 69% at Spezia was the best among center-backs in the bottom half of the table.

How Kiwior's Role Differs from Past Polish Defenders

Kamil Glik was a classic stay-at-home defender: strong in the air, but limited on the ball. He rarely stepped out of the defensive line, preferring to absorb pressure and clear. Kiwior is different. He averages 1.8 interceptions per game, a figure that reflects his willingness to read play and step forward to intercept passes before they reach the striker.

This proactive style carries risk. When Kiwior steps out and misses the interception, the space behind him is exposed. Against quick forwards, that can be fatal. But his recovery speed—estimated at roughly 31 km/h in sprint—is better than Glik's ever was, and his 3.0 progressive carries per 90 minutes show he can drive the ball out of defense, bypassing the first line of pressure.

Jan Bednarek, by contrast, is more conservative. He averages only 0.9 progressive carries and relies on short passes to escape pressure. That makes him a good complement to Kiwior: one steps out, the other covers. In Poland's 3-1 win over Scotland in a Euro 2024 qualifier, the duo started together and conceded zero set-piece goals, with Kiwior winning seven aerial duels and Bednarek making five clearances.

Another difference is Kiwior's ability to build from the back. His pass completion rate of 91% at Arsenal includes a high volume of line-breaking passes into midfield. That skill allows Poland to bypass the opposition press more effectively than when Glik was in the side, when the ball often went long to Robert Lewandowski.

System Fit: Probierz's Pressing Trap Needs Aerial Coverage

Michał Probierz, appointed in 2023, has implemented a pressing system that asks Poland's defenders to step up and compress space. The high line leaves the team vulnerable to long balls over the top, especially when the press is broken. In 2023, Poland conceded nine goals on the counter-attack, a figure that tied for worst among European teams in World Cup qualifying.

Kiwior's aerial ability is the safety net that system requires. When an opponent launches a long ball to bypass the press, Kiwior can step forward and win the header, resetting the defensive shape. Against the Netherlands in a Nations League match in September 2024, he made three such headers outside the box, each time preventing a 2-on-1 situation.

The trade-off is that Kiwior's aggression can leave him out of position if the header is flicked on. Against Croatia in Euro 2024 qualifying, he lost a flick-on that led to a goal. Probierz has since adjusted, assigning a midfielder to drop in behind Kiwior when he steps out, a tactic that has reduced those vulnerabilities.

Some observers argue that Poland's problems are not purely aerial. The team also struggles to defend quick combinations in tight spaces. Kiwior's 1.8 interceptions help, but he is not a natural one-on-one defender against agile dribblers. In the 2024-25 Champions League, he was turned by a quick forward from PSV Eindhoven, leading to a goal. Probierz may need to pair him with a more mobile partner, such as Sebastian Walukiewicz, in certain matchups.

2026 Group Stage Opponents Threaten in Air

Poland's 2026 World Cup group includes the Netherlands, Croatia, and a playoff qualifier. The Netherlands average 1.87 meters in height across their likely starting eleven, with defenders like Virgil van Dijk and Nathan Aké both dangerous from set pieces. Croatia relies heavily on set-piece routines, scoring six goals from dead-ball situations in Euro 2024 qualifying.

The aerial battle between Kiwior and Josko Gvardiol—himself a strong aerial defender—could be decisive. In their last meeting, a Nations League match in 2023, Gvardiol won four aerial duels to Kiwior's three, but Poland's center-back had a higher clearance rate. Data from that match shows Kiwior made three headed clearances inside the six-yard box, each under pressure.

Against the playoff qualifier, likely to be a team from Asia or Africa, Poland will face different aerial challenges. African teams often use powerful target men who excel at holding up the ball. Kiwior's 72.4% win rate suggests he can handle that, but he has limited experience against physically dominant strikers in international football.

One concern is that Kiwior's aerial stats come primarily from club football, where set-piece routines are more structured. International teams often use simpler, more direct deliveries that can be harder to read. In Euro 2024, Kiwior's aerial win rate dropped to 63%, still good but not elite. That gap suggests the transition to international football is not seamless.

Potential Partnership: Kiwior and Bednarek's Complementary Skills

When Kiwior and Bednarek started together in three World Cup qualifiers in 2024, Poland conceded zero set-piece goals. Their combined average of 11.2 clearances per game was the highest of any center-back pairing in European qualifying. Bednarek's reading of danger—he averages 2.3 interceptions per 90 for Southampton—allows Kiwior to attack the ball more aggressively.

The pairing has a natural division of labor. Kiwior covers the left channel, where his stronger foot allows him to clear with his left when under pressure. Bednarek stays central, using his experience to organize the backline. In the 1-0 win over Austria in October 2024, Kiwior made eight aerial wins, while Bednarek made six clearances and blocked two shots.

But the partnership has weaknesses. Both defenders are vulnerable to pace in behind. Against a team like the Netherlands, which can field wingers like Xavi Simons and Donyell Malen, the high line could be exposed. Kiwior's recovery speed is adequate but not elite; Bednarek's is below average. Probierz may need to drop the defensive line deeper in those matches, reducing the effectiveness of his pressing trap.

An alternative is to use Kiwior as a left-sided center-back in a back three, with Bednarek central and a faster right-sided defender like Walukiewicz. That formation would give Kiwior more cover to step out and win headers, while the extra center-back provides insurance. Poland used this shape in a friendly against Germany in March 2024, winning 2-1, with Kiwior winning five aerial duels.

Practical Adjustments for Michał Probierz's Set-Piece Drills

Probierz can make specific tactical adjustments to maximize Kiwior's aerial strengths. Assigning him to mark the opposition's tallest target man—such as Van Dijk or Croatia's Mario Pašalić—would put his 72.4% win rate to its best use. In training, drills that simulate flick-ons and second balls would prepare Kiwior for the chaos of international set pieces.

Poland currently uses zonal marking on corners, with Kiwior as a deep-lying sweeper. That role allows him to read the flight of the ball and attack it at its highest point. Against teams that favor short corners, however, the zonal system can leave gaps. In Euro 2024, Austria scored from a short corner routine that pulled Kiwior out of position. Probierz may need to assign a specific man-marking role for Kiwior in those situations.

Another adjustment involves set-piece attacking. Kiwior's 93% pass accuracy in build-up play means he can be a target for short corners, receiving the ball and then crossing or shooting. He scored a header from a corner for Arsenal against Burnley in 2023, and his 1.8 goals per season from set pieces is respectable for a center-back. Using him as a decoy runner could create space for Lewandowski or others.

Counter-Arguments and Limitations: Not a Panacea

Despite Kiwior's impressive numbers, some analysts question whether his aerial dominance alone can solve Poland's defensive issues. His 72.4% win rate, while excellent, comes in a system at Arsenal that emphasizes zonal marking and coordinated pressing. In the Polish national team, where defensive organization has been inconsistent, Kiwior may not receive the same support. For example, against Albania in a World Cup qualifier in November 2024, Kiwior won 80% of his aerial duels but Poland still conceded a goal from a corner when Bednarek failed to clear the second ball. That goal highlighted that set-piece defense is a team effort, not just one player's responsibility.

Another limitation is Kiwior's susceptibility to being drawn out of position. In a match against Moldova in October 2024, Kiwior stepped up to win a header near the halfway line but mistimed his jump, allowing the striker to run through and score. Such errors have occurred in roughly 1 in 10 matches for Poland, according to post-match analysis. Probierz has worked on having a midfielder drop into the vacated space, but the coordination is still developing.

Additionally, Kiwior's aerial win rate against physically dominant strikers in international football is less proven. In Euro 2024, he faced Romelu Lukaku in a friendly and lost three of five aerial duels, a reminder that elite target men can still trouble him. Poland's group stage opponents in 2026 include tall forwards like Memphis Depay and Andrej Kramarić, who are not aerial specialists but are strong in the air. Kiwior will need to adapt his timing and positioning for different styles.

Some pundits argue that Poland's focus on aerial defense may be misplaced. The team conceded more goals from open play (12) than from set pieces (7) in 2022, and their defensive transition remains a weakness. Kiwior's progressive carries can help, but they also expose the defense if he loses possession. In a Nations League match against Belgium in 2023, Kiwior attempted a dribble near his own box, lost the ball, and conceded a penalty. Probierz has since instructed him to prioritize safety over risk in deep areas.

Broader Context: Poland's Defensive Evolution Since 2022

Since the 2022 World Cup, Poland has gradually shifted from a reactive, deep-block defense to a more proactive high press. This evolution, driven by Probierz, requires defenders who can both win aerial duels and contribute to build-up play. Kiwior fits that mold, but he is not the only option. Sebastian Walukiewicz, who plays for Empoli, has improved his aerial win rate to 65% in the 2024-25 season and offers better pace in recovery. However, Walukiewicz lacks Kiwior's passing range and composure under pressure.

Another emerging option is Mateusz Wieteska, who has a 70% aerial win rate at Clermont Foot but is less experienced at the international level. Probierz has used Wieteska as a substitute in three qualifiers, with mixed results. The depth chart suggests that Kiwior is the first-choice, but his position is not guaranteed if his form dips or if tactical adjustments require a different profile.

Poland's defensive record in 2024 offers some optimism. In 10 matches, they conceded only eight goals, with five clean sheets. Kiwior started in seven of those matches, and the team conceded set-piece goals in only two of them. That is a significant improvement from 2022, when they conceded set-piece goals in four of five matches. The data suggests that Kiwior's presence has already made a difference, but the sample size is small, and tougher tests await in 2026.

Conclusion: A Specialist, Not a Savior

The broader lesson is that Poland's defensive plan for 2026 cannot rely solely on Kiwior. He is a specialist, not a savior. His aerial numbers are elite, but they exist within a system that must compensate for his occasional positional lapses and lack of elite pace. If Probierz can build a defensive structure that maximizes Kiwior's strengths while covering his weaknesses, Poland may finally solve the set-piece problem that haunted them in 2022. The 2026 World Cup will be the ultimate test of whether that structure holds under pressure.
