Chelsea spent £15.6 million to sign Aarón Anselmino from Boca Juniors in August 2024. The Argentine centre-back, born April 29, 2005, has been shuffled through a series of loan deals: first back to Boca Juniors, then to Borussia Dortmund, and now to Strasbourg. All while Chelsea keeps a tight grip on his seven-year contract and refuses to let anyone buy him outright.

The Dortmund chapter

Anselmino landed at Borussia Dortmund on loan on August 27, 2025. The results were modest but not insignificant: 10 appearances, 1 goal.

Dortmund wanted more. The German club pushed to convert the temporary arrangement into something permanent, signaling they saw enough in those 10 outings to justify a longer commitment.

Chelsea said no.

On January 26, 2026, Chelsea exercised a recall clause in the loan agreement. The clause was reportedly tied to a minimum-minute threshold, meaning Anselmino hadn’t logged enough playing time at Signal Iduna Park to keep the arrangement intact.

The loan carousel and what it means

Anselmino is now at Strasbourg, the French club that, like Chelsea, sits within the broader constellation of BlueCo’s multi-club ownership model. Sending a young player to an affiliated club gives Chelsea maximum control over development, playing time, and tactical education without actually integrating him into the first-team squad at Stamford Bridge.

The £15.6 million Chelsea paid Boca Juniors looks like a bet on future value rather than immediate first-team need. Anselmino was 19 at the time of the transfer. He’s now 21 and has played competitive football in Argentina, Germany, and France without ever pulling on a Chelsea shirt in a meaningful capacity.

Dortmund’s interest complicates the picture. Their willingness to pursue a permanent deal suggests they genuinely rated the player. Being told no by Chelsea, even after limited playing time, tells you everything about how London values the asset on their books.
