The champions have confirmed that Dembele has suffered a hamstring injury and will undergo tests on Sunday to determine the severity of the problem.
Valverde was asked about the Frenchman after the match and gave an update:
“With Dembele, it looks like a tear. We had already noticed during the play that something was not right.
”We were worried quickly because it seems like a muscular tear. It is certainly not muscle fatigue because the other day he played very little.
”These things happen and as a coach I do not have an explanation.”

If the injury is as bad as Valverde fears then it seems as though Dembele’s season is over, and the champions will have to cope without him for the rest of the campaign.
