Chelsea yank Anselmino back from Dortmund as Rosenior shores up a creaking back line

Chelsea are moving quickly in January, and David Ornstein says the Blues have pulled the lever to bring Aaron Anselmino back from Borussia Dortmund. It’s a pragmatic play from a club feeling the pinch at centre-half, and one that tells you Liam Rosenior wants bodies — and quality — in the building right now.

The Ornstein line: recall clause activated

Per The Athletic’s Ornstein, Chelsea have triggered a recall clause on the 20-year-old Argentine as they size up the centre-back market this month. BlueCo are taking a hard look at their defensive depth and, crucially, their options for both the present and the run-in. The club also held a similar option on Mamadou Sarr but chose Anselmino, while highly rated Josh Acheampong is set to remain — any permanent exit is viewed as a non-starter despite Crystal Palace interest.

Strategically, it fits. Sarr — signed on an eight-year deal from sister club Strasbourg — is continuing his development back in Ligue 1, with Strasbourg ticking along nicely in seventh. If someone’s season is going to be disrupted, better Dortmund than your own in-house project.

Who is Aaron Anselmino and where’s he up to?

Signed in 2024 from Boca Juniors for around £15.6m, Anselmino initially returned to La Bombonera on loan before being recalled in January. He hasn’t yet featured in the Premier League, but he did get a late run-out for Chelsea at the Club World Cup against Benfica. The plan for this season was regular minutes at Dortmund, but a stop-start spell with injuries has limited him to 10 appearances. He’s just back fit, and Chelsea have seized the moment.

Why Chelsea need him now

Levi Colwill’s long-term absence stings, and Tosin Adarabioyo is also on the treatment table. Rosenior has leaned on a back four, with Benoît Badiashile and Trevoh Chalobah starting against Crystal Palace, while Wesley Fofana and Jorrel Hato came on to steady the ship and Acheampong stayed in reserve. With Chelsea still fighting on four fronts, depth isn’t a luxury — it’s non-negotiable.

January implications: cover, competition, or fresh shop window?

This recall gives Rosenior choices. Anselmino can provide immediate cover, push competition levels at Cobham, or even be re-routed if the market throws up a late opportunity. The bigger picture is Chelsea evaluating the centre-back landscape without committing to a panic buy. If the price isn’t right elsewhere, they’ve at least brought a highly regarded young defender back into their orbit.

Scouting snapshot

Anselmino reads the game well, is tidy on the ball, and relishes front-foot defending — traits that suit Rosenior’s preference for a proactive line. Fitness is the watchword; get him humming, and he can eat useful minutes while others heal. If not, the recall still restores control of his development arc.

Pundit’s verdict

It’s sensible, low-risk squad management. Chelsea secure another centre-half option during a defensive squeeze without writing a big cheque. Dortmund won’t love it, but needs must at Stamford Bridge. If Anselmino strings together training ground form and stays fit, he’ll be more than a break-glass option — he’ll be part of a spring push.

For those eyeing the January hustle from a punter’s angle, our best betting sites rundown is a handy pit stop — but the shrewdest wager right now is on Chelsea prioritising defensive stability with Anselmino back in blue.
