It’s official (basically): Takehiro Tomiyasu is a Crystal Palace player. Fabrizio Romano gave it the “here we go” late on Wednesday night, making the Japanese international Pierre Sage’s second free transfer of the window after Oscar Mingueza. While we may all be familiar with the name, this article will dive deeper into his background, the unavoidable injury concerns, and his overall fit in Sage’s system.

This transfer has been the worst-kept secret at Selhurst as of late, with Tomiyasu seen training with the squad throughout pre-season, even featuring in our latest 3-1 friendly win over Al-Ula in Como. Despite only featuring for 30 minutes, this allowed for Sage and his medical staff to take a proper look at the player’s profile and fit, rather than gambling solely off reputation.

A FAMILIAR NAME: WHO IS TAKEHIRO TOMIYASU?

Tomiyasu spent four years at Arsenal after a near £20m move from Bologna in the summer of 2021, making 84 appearances across all competitions and quickly establishing himself as a fan favourite in North London. Valued for his positional intelligence and ability with both feet, Tomiyasu is comfortable in any position across the back line, possessing the skillset necessary especially to operate in a back three.

Unfortunately, it is impossible to ignore his injury history. Tomiyasu’s medical file at Arsenal does not make for pretty reading, sustaining injuries to his calf, thigh, hamstring, and knee, often on multiple occasions. Knee surgery in February 2025 wiped out almost his entire final season at Arsenal, restricting him to a handful of minutes before the club and player mutually agreed to terminate his contract, allowing him to focus purely on rehab.

Following a six month spell without a club, Ajax offered him a short-term chance to prove he could still thrive at the highest level in December 2025. Worryingly, his tenure in the Netherlands was disrupted with further fitness setbacks, limiting him to just 236 minutes across 9 matches. Ajax’s Director of Football Marijn Beuker was upfront about their concern at the time of the signing: “his injury history was also an important consideration.”

Despite the adversity, Tomiyasu forced his way into the 26-man Japan squad for this summer’s World Cup; his first major tournament involvement since the 2022 rendition. He made three appearances in Group F at an average match rating of 7.2; clear evidence that, when fit, he can still perform at a consistently-high level. Now 27, he arrives at Selhurst Park off the back of a solid tournament run rather than off a season on the treatment table, which is a meaningfully different starting point to where he was twelve months ago. Here’s hoping that translates onto the pitch.

DOES HE SUIT SAGE’S SYSTEM?

Presuming Sage sets up Palace in his traditionally 3-4-2-1 system, morphing into the 3-2-5 in attack, Tomiyasu’s fit will be measured under the same principles stated in my previous Krepin Diatta article: playing out cleanly from the back, constantly attacking the space behind the opposition, and pressing hard to win the ball back fast. The new-look back three needs centre-backs comfortable receiving the ball under pressure while also progressing possession forward. The two wide centre-backs will also be asked to step out and defend the wide channels, often one-on-one, whenever Muñoz or Mitchell are caught out upfield.

This fits Tomiyasu’s profile. Two-footed, comfortable under pressure, and possesses the positional discipline to defend in isolation out wide; all qualities that shone through when he was at his best for Arsenal. He can play as either of the two outside centre-backs in our back three, or even drop into a more conventional full-back role if Sage needs to switch to a back four mid-match, a concept he flirted with during their Como Cup fixtures. Tomiyasu hasn’t been signed as a focal point for our defence, he’s been signed for his versatility.

He also offers cover at right wing-back behind Muñoz, a role that requires a serious physical presence in this system and one that visibly exhausted Rio Cardines across pre-season. While we can’t expect the Japanese international to replicate Muñoz’s attacking output, he serves as a solid emergency defensive option that could become vital with our overwhelming fixture list this season. Tomiyasu’s arrival likely opens the door for Cardines’s seemingly imminent loan move to Bristol City; a benefit for all parties involved.

But, as we all know, football doesn’t just come down to how good your system is on paper. There’s a human element to it too. Tomiyasu joins a dressing room that includes fellow Japan international, and close friend, Daichi Kamada, who recently extended his own one-year contract extension with Palace. A dressing room that already has a former teammate, fellow countryman, and longtime friend in it can only help make Tomiyasu feel at home.

THE FINAL VERDICT

In essence, this looks to be a sensible, risk-free addition of proven Premier League quality to a defensive unit about to be stretched across four competitions. Yes, the injury history is real, and it’s glaringly obvious too, but if he can find his footing and stay fit and ready, there’s no reason he can’t become a pivotal member of our squad across both domestic and European campaigns this season.

If Tomiyasu can string together a run of fitness, Palace have added a defender capable of playing three positions to an elite standard, all for free. If the injuries return, or seemingly ‘when’, the downside is limited too. For a club whose recruitment model has increasingly been built around this sort of ‘low-risk, high-upside’ strategy, it’s hard to complain about this piece of business.
