Chelsea’s Aaron Anselmino Joins Borussia Dortmund on Loan

Chelsea have confirmed that young defender Aaron Anselmino has joined Borussia Dortmund on loan for the 2025/26 season.

The 19-year-old was signed from Boca Juniors in 2024 after a string of impressive performances in Argentina, penning a long-term deal with the Blues. He initially returned to Boca on loan, where he made 18 appearances, before being recalled to Stamford Bridge in January.

Anselmino was also part of the Chelsea squad that lifted the FIFA Club World Cup in 2025, marking an early career highlight before his next development step.

Chelsea described the loan switch in a club statement, confirming the teenager will continue his progress in the Bundesliga, a league known for nurturing young talents.

Opinion: A Smart Move for Both Chelsea and Anselmino ✨

This deal feels like perfect timing for both club and player. Anselmino has shown promise but needs regular top-level football to sharpen his game — and at Chelsea, competition for defensive spots is fierce under Enzo Maresca.

Borussia Dortmund, on the other hand, have a proven track record of developing young players and giving them the stage to flourish. From Jadon Sancho to Jude Bellingham, the German giants have consistently offered young stars the minutes and responsibility they need.

For Chelsea fans, it’s not goodbye but rather a strategic investment in Anselmino’s growth. If he thrives in Germany, he could return to Stamford Bridge ready to stake a claim as a long-term defensive option — or even increase his market value.

It’s a reminder that Chelsea’s project is not just about buying talent, but also about smart player development. And for Anselmino, this could be the loan spell that defines his path to becoming a true star.
