Erik ten Hag admits there could come a point where Manchester United have to accept it has not worked with Donny van de Beek but has insisted he still has faith he can do better.
Van de Beek made his first start for United since December 8 in the 1-0 Europa League win over Real Sociedad but he only lasted 58 minutes.
The 25-year-old recently returned from a seven-week lay-off with a muscular injury and his role behind Cristiano Ronaldo in San Sebastian appeared to be a trial ahead of potentially replacing the suspended Bruno Fernandes at Aston Villa on Sunday.
