'Really hard on him' - Ruben Amorim explains why Manchester United player doesn't fit his system

Ruben Amorim has cast doubt on Tyrell Malacia's long-term future at Manchester United after claiming he lacks the attacking quality to play as a wing-back in his system.

The Dutch defender made his fifth start since returning from 18 months out with a knee injury against FCSB on Thursday, but for the fourth time he was withdrawn at half-time after a difficult evening at the National Arena.

The 25-year-old is likely to leave Old Trafford on loan before Monday's transfer deadline, with Real Betis one of several clubs interested in offering him the chance to build up his fitness and confidence. His opportunities will become more limited at United with the imminent arrival of 20-year-old Dane Patrick Dorgu from Lecce.

Amorim believes Malacia doesn't currently have the attributes needed to play as a wing-back, and while he hinted at a potential role in the back three, that could only happen when United become a more possession-dominant team.

"He can play as one of the three defenders, if we have more possession and more control of the games. It's a really difficult context for him. But he's our player and we are
