Manchester United will potentially be sweating over the fitness of Harry Maguire for their Europa League final with Villarreal on May 26.
The Red Devils captain was previously ever-present in Ole Gunnar Solskjaer's defence in the Premier League, but he had to be forced off with 78 minutes on the clock against Aston Villa on Sunday.
The former Leicester City man tried to carry on before limping off the pitch in a worrying sight for United supporters, and he is almost certain to miss Tuesday's game with his old employers.
According to journalist Henry Winter, Maguire was spotted with a support boot on his left foot while heading for the team bus after the game, sparking fears that he may not be fit for the Europa League final later this month.
Solskjaer is already having to make do without Daniel James, Phil Jones and Anthony Martial, and the Red Devils must now navigate fixtures with Leicester and Liverpool within 48 hours of each other.
Victory over Aston Villa saw United move 10 points behind Manchester City in the table, but the Citizens will be crowned champions if Leicester beat the Red Devils on Tuesday night.
