Ruben Amorim fears Benjamin Sesko may have suffered a serious knee injury in Manchester United’s draw at Tottenham.
United’s £73.7million summer signing came on as a 58th-minute substitute, but went off half an hour later limping heavily.
Amorim will have to wait for an update on Sesko’s condition, but admitted that he is concerned about the situation.
Asked if it might be serious, the United boss replied: ‘I have no idea. Because it’s the knee, we never know.
‘I’m concerned with the injury because it's in the knee. We need Ben to be a better team.
