Jose Mourinho has confirmed that Antonio Valencia suffered a hamstring injury in the second half of Manchester United's victory over West Bromwich Albion on Sunday.
It was the seventh successive game that Valencia, who has been wearing the captain’s armband in Michael Carrick’s absence, has started and the boss feels his injury is the result of him playing in a number of matches in a short period of time.
"This is what I call a December injury. It is an injury of accumulation of fatigue. It is a muscular one. Hamstring. Big, small, medium, I don't know. Let's wait."
Speaking in his post-match press conference, the boss said: “This is what I call a December injury. It is an injury of accumulation of fatigue. It is a muscular one. Hamstring. Big, small, medium, I don't know.”
When asked how long the no.25 might be out for, he added: “Let's wait. I think he is an experienced guy to not let it go to difficult limits. But it is an injury of fatigue. Everyone in the Premier League especially the ones in more accumulation of cups, European cups, they are at risk.”
The Reds face Championship side Bristol City at Ashton Gate in the Carabao Cup quarter-final on Wednesday night before returning to Premier League action away at Leicester City next Saturday, 23 December, as United embark on a busy run of fixtures over the festive period.
