Manchester United forward Amad Diallo could miss the rest of the season with ankle ligament damage, the PA news agency understands.
PA understands the Ivory Coast international is still being assessed, but a United source indicated it is touch and go whether he will play again this season.
Reports subsequently emerged that United midfielders Kobbie Mainoo, Manuel Ugarte and Toby Collyer picked up injuries in addition to Diallo’s setback.
Lisandro Martinez recently sustained a season-ending anterior cruciate ligament injury, while Amorim suggested Luke Shaw, Jonny Evans, Mason Mount and Altay Bayindir remain absent.
As if they were not dealing with enough, PA understands United’s travel plans to the capital were disrupted by a signal failure on the West Coast mainline.
