Ruben Roosken has left Huddersfield Town in a transfer deadline day move to Championship side Oxford United. The move is an initial loan for the rest of the season with an obligation for Oxford to buy him in the summer. In a club statement, Manning said that Ruben's departure is in the best interests of all parties involved. He stated that given their strength in depth on the left, the player was unlikely to be satisfied with his playing time, and a deal has been agreed that allows him to join another good club. Sporting director Chris Markham added that Oxford United displayed a strong desire to make this deal happen. He also said that with the terms including a clause to make the transfer permanent, all parties have clarity for the future and they wish Ruben the best of luck with his new side.

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.
