Ousmane Dembele was forced off due to injury in Barcelona’s 1-0 win over Girona on Saturday in what is a big blow to the Catalan giants.
Xavi offered a brief update on his attacker after the match after losing the Frenchman to what looked to be a muscular problem.
“Dembélé? I think there is a significant injury,” he said.
“It’s a shame, because he is one of the most decisive footballers for us, the most differential.
“We will see the tests, but he has noticed something. We hope it’s as little as possible, but he has noticed a quadriceps injury.
