More problems for Barcelona: Vermaelen injured Umtiti could return The international break has not been kind to Barcelona, and Thomas Vermaelen will undergo tests on Monday to determine the extent of an injury he sustained on Friday while with Belgium. Vermaelen has been released by his national team to travel back to Catalonia where he will be examined by his club. At the moment all that is known is that the injury is to his hamstring. Saturday’s game against Sevilla is almost certainly an impossibility for the defender, whose injury comes as a headache to Ernesto Valverde and Barcelona. They already have fitness problems at the back with Samuel Umtiti and Sergi Roberto.
