Quique Setien reportedly faces a fight to keep his job at Barcelona after losing the faith of the dressing room.
While the Catalan giants have recorded 11 points from five games since the resumption, they have under-performed in their last four outings, resulting in the advantage being handed to Real Madrid in the title race.
After twice letting go of a lead at Celta Vigo on Saturday, Marca claims that Setien's relationship with his players has broken down.
The report suggests that many squad members are not listening to Setien's instructions, which appear to be left to assistant Eder Sarabia at drinks breaks during matches.
The former Real Betis man, who was only appointed as Ernesto Valverde's replacement in January, is said to be struggling to resolve the situation.
Barcelona's next two games come against Atletico Madrid and Villarreal, two teams currently in form in La Liga.
