Veerle Buurman: A closer look at Chelsea's defensive revelation

Veerle Buurman has had no time to ease into English football. The 19-year-old has been thrown into Chelsea's starting lineup following injuries to both Millie Bright and Naomi Girma, asking her to fill some of the most significant shoes in the Barclays Women's Super League at a club competing on four fronts. She’s made 10 league starts, five in the Champions League, and appeared in both domestic cups, and has not looked out of place in any of them.

For a teenager in her first season of senior English football, the level of performance has been quietly remarkable. Buurman is composed on the ball; she is aggressive without being reckless, good in the air, and rarely looks hurried, regardless of the occasion or the opponent. There is a calmness about her that is reassuring, despite her young age.

That none of this has come as a total surprise to those who had followed her trajectory says something about the player Chelsea identified when they signed her in September 2024.

Buurman joined the defending BWSL champions on a four-year deal at 18, after a single season in PSV Eindhoven's first team. The plan was that she would return to PSV on loan, let her develop at the highest level Dutch football could offer, and then bring her into the Chelsea fold once she was ready.

The injury crisis the Blues have faced perhaps forced Sonia Bompastor’s hand, but in Buurman, she has a defender who seems unfazed by anything. Deployed at both centre back and left back, the Dutch international has proven that she is more than capable of handling the pressure at the highest level.

In this analysis, we look at what the data tell us about her season so far, where her strengths lie, and why, at 19, she is already one of the most exciting young defenders in the league.

The data

Before diving into the analysis, the pizza chart above offers a useful overview of where Buurman stands relative to her BWSL positional peers across attacking, progression, and defensive metrics this season.

It is worth noting from the outset that Buurman has not exclusively played at centre-back, as she has started at left-back in a few games, which will influence some of the progression numbers in particular. With that context in mind, the picture it paints is compelling for a 19-year-old in her debut season with Chelsea.

Defensively, the chart is strongest where you might expect it to be. Her possession-adjusted interceptions rank at the 90th percentile, a figure that speaks directly to the defensive intelligence and positional awareness we will explore in detail below.

Meanwhile, sliding tackles are at the 80th percentile, while aerial duels and win percentage are both at the 79th percentile. The defensive duel metrics are the one area where the chart dips noticeably, suggesting this is an area for development within her game.

In terms of ball progression, the numbers are eye-catching. Progressive runs rank at the 93rd percentile among BWSL centre-backs, a figure partly influenced by her appearances at left-back but impressive regardless of context, whilst she is also significantly above average for progressive passes.

Additionally, the attacking metrics are perhaps the most surprising element of the chart. Her expected assists rank at the 89th percentile, underlining just how consistently she contributes to Chelsea's attacking play.

For a teenage defender thrown in under difficult circumstances, these numbers set the tone for everything that follows.

Defensive positioning

Of course, when talking about defenders, we immediately look at their positioning and ability to cut out opposition attacks. A defender's off-the-ball qualities are rooted in their footballing intelligence and the ability to read the game, anticipate where danger is developing, and get there before it arrives, which is often what separates those who are constantly firefighting from those who make the game look straightforward.

Buurman shows it in abundance. For a player operating in Chelsea's system, yes, she has the freedom to influence attacks, but what has really stood out, especially when playing as a centre back, is her ability to make vital interceptions.

The 19-year-old averages 7.3 possession-adjusted interceptions per 90 so far this season. She possesses defensive intelligence in abundance, something which has been key for Sonia Bompastor's side as their BWSL campaign has been anything but simple.

Here, we can see just how well Buurman reads the game. Brighton play a low, driven ball through the lines, and the Chelsea defender uses her speed, showcasing an excellent burst of acceleration, to get there ahead of her opponent and cut out the pass, preventing Brighton from getting in behind the defensive line.

Moreover, she stays calm even with two Brighton players putting her under pressure, laying the ball off to Baltimore, who can turn and start to build an attack for Chelsea.

Buurman's positioning and reading of the game is exemplary, whether playing at centre-back or left-back. Here, we can see her on the left side of a back four, anticipating Spurs' build-up play. Seeing where Beth England is going to play the ball, the Dutch defender moves quickly to cut out the pass and prevent Tottenham from building an attack down the flank.

Sonia Bompastor is a manager who demands her defensive line be active and aggressive rather than passive and reactive, and Buurman's ability to read and intercept play is precisely the profile she needs.

Buurman’s reading of the game and her propensity to cut out attacks before they develop allow Chelsea to maintain their defensive line higher up the pitch, just as Bompastor wants, thereby compressing the space available to opposition midfielders and keeping the team's structure intact.

It also means that attacking transitions can be executed more quickly. Buurman’s astute positioning means that Chelsea can recover possession higher up the pitch and catch their opponents on the counterattack, giving them another attacking edge.

Progressive play

A modern centre-back is not simply a defender. The best in the game are as comfortable initiating attacks as they are stopping them, and the ability to progress the ball quickly from deep is increasingly one of the most valued qualities a defender can possess. For Veerle Buurman, this is an area where she stands out.

Buurman averages 58.06 passes per 90 in the league this season, comfortably above the league average for centre-backs of 48. That figure alone is significant, but volume without quality tells you little. What makes her numbers compelling is the accuracy that underpins them.

She completes 87.3% of her passes, and her forward pass accuracy is 80.5%, meaning she is not simply recycling possession sideways and backwards but consistently looking for teammates in advanced positions and completing those passes at a high rate.

In this instance, we see a clear example of her willingness to play progressive passes. She receives the ball and, whilst she has time and space to assess the situation in front of her, the left-footed defender plays an incisive pass through the West Ham lines, cutting out the midfield and in behind the defensive line for her teammate to run onto.

Her progressive passing numbers reinforce just how composed she is on the ball. Buurman averages 9.75 progressive passes and 8.61 passes into the final third per 90. She is regularly driving play forward from deep, threading passes through the lines with purpose.

One thing that is always impressive when watching Veerle Buurman play is just how comfortable she is on the ball when teams look to press her. She doesn’t panic or rush just because pressure is mounting.

Here, with Liverpool pressing aggressively, we can see that the passing lane to Bright is closed off, and the option in front of her is cut out. Rather than forcing the ball into a tight space or playing a risky sideways pass, Buurman shifts the ball away from the oncoming defender and uses her body to shield the ball.

She uses quick feet and a change of pace to create just enough separation to execute a long ball forward, evading the Liverpool press entirely and turning a moment of defensive pressure into an attacking opportunity for Chelsea.

Buurman also contributes with the ball at her feet, averaging 1.66 progressive runs per 90. This adds another dimension to Chelsea's attacking play, giving Bompastor's side an extra option to advance up the pitch and create numerical advantages in transition.

Her willingness and ability to carry the ball out from defence with conviction speaks to the same confidence that defines her defensive work. This is perhaps most evident when Buurman is deployed at left-back, where her ability to carry becomes a real attacking weapon for her team.

Here, she receives the ball wide on the left touchline, uses her strength to evade a challenge, and carries it deep into the attacking third, forcing Spurs back. What is notable is the Tottenham defenders' reluctance to step in and challenge her.

Buurman is physically imposing for her age and exceptionally difficult to hustle off the ball, and Spurs know it. Rather than risk being beaten, they retreat, ceding ground and inviting Chelsea further forward.

Across both her passing and her carrying, she demonstrates an understanding of when and how to progress the ball; she’s proving she can make the right decisions in terms of ball carrying, giving Chelsea another edge when they look to build attacks.

1v1 defence

If there is one area of Buurman's game that offers room for improvement, it is her 1v1 defending. The issue here is not one of effort or physicality. Buurman is strong, aggressive, and willing to engage.

She sometimes struggles with judgment of the situation in front of her, specifically knowing when to stick tight to an opponent and when to drop off. It is one of the most difficult decisions a defender makes, and it’s one that tends to improve significantly with experience at the highest level.

Here, against Brighton, we see the problem illustrated clearly. Buurman is drawn into a 1v1 situation against Rosa Kafaji. The young defender wants to stop her opponent from going down the line on her right foot, so she decides to stick tight to her opponent.

Rather than forcing the issue, Kafaji uses that proximity against Buurman, spinning away from the challenge and cutting back inside onto her left foot. This forces Baltimore to leave her runner and close the space to prevent Kafaji from executing a shot, which then enables the Brighton attacker to play a quick pass into the player Baltimore had to vacate to limit Kafaji's options.

Buurman's engagement here makes Kafaji's decision for her. Had Buurman dropped off slightly and kept the opponent in front of her, it would have been up to Kafaji to make the decision, and she may not have been as decisive. It would also have given Buurman the opportunity to recover possession, block the cross, or affect the shot rather than being eliminated from the play entirely.

It is worth stressing that this is a common trait in young defenders early in their careers. The instinct to press and engage is a good one, and learning when to suppress it is simply a matter of experience; there is little reason to doubt that Buurman, given the pace of her development so far, will not add that to her game sooner rather than later.

Conclusion

The measure of a young player is not about how they perform when everything is going well; it’s more about how they perform when the circumstances are difficult and the stakes are high. By that measure, Veerle Buurman has answered every question asked of her this season.

What makes her profile so compelling is the combination of defensive intelligence and positional awareness that enables her to fit into a Chelsea side that looks to press aggressively and transition quickly. Her composure and technical quality on the ball make her a creative outlet from deep, while her ability to carry the ball forward shows how versatile and composed she is for such a young player.

She is a 19-year-old player in her first season of English football. There’s still development needed, but from what we have seen so far, it’s a matter of refining decision-making, and with the coaching environment and competitive exposure that Chelsea provides, there is every reason to expect that to improve.

For Bompastor, her young defender has stepped up when Chelsea needed her most. The season may not have gone how the Blues envisioned in the BWSL, but Buurman's performances have been one of the clearer positives to take from it.

Looking ahead, it is impossible to say how the Chelsea squad will be shaped next season. Whatever the defensive setup, Veerle Buurman has made herself impossible to leave out.
