The 19-year-old England international has yet to feature in Manchester United's opening two matches of the 2025-26 season, against Arsenal and Fulham. This lack of game time has led to speculation that Mainoo may be loaned out to another team.

Several Premier League clubs, as well as the Spanish sides, are reportedly interested in signing Mainoo on a season-long loan. Manchester United will face Grimsby Town in the second round of the Carabao Cup and then host Burnley in the Premier League on August 30.
