Alejandro Garnacho has been told he can leave, which suggests he will not return for pre-season training early in July.
There is interest in the young Argentina international. The same is also true of England midfielder Kobbie Mainoo, although United are more minded to keep him.
Turkey goalkeeper Altay Bayindir might be one to watch. He now knows he will not be United’s first choice, having lost out to Andre Onana in the Europa League final and, in World Cup year, is eager to get regular first-team football again.
