Oxford United, which is 23rd in the Championship, is attempting to sign 25-year-old Dutch-Angolan defender Ruben Roosken from Huddersfield. The left-back has developed into a key player, and his performances have reportedly drawn Oxford's attention. The club wants to finalize a loan deal that includes an option to buy on Monday, as the transfer window in England shuts at 20:00. The potential transfer is also dependent on Roosken passing a medical examination. Roosken joined Huddersfield in January 2025, and his contract is valid until June 2028. In the current League One season, he has made 21 appearances, scoring one goal and providing two assists. His current Transfermarkt market value is €700k.
