Isidor: This coach has made difference for Sunderland players

Forsythe joined Sunderland in the summer from Borussia Dortmund.

“The intensity is crazy,” Isidor told L'Equipe.

“We’re coming off a tough pre-season with few wins, then we beat West Ham.

"The turning point was that the coach brought us a performance manager, who had been at Arsenal and Dortmund.

“He arrived just before the first league match, and he changed a lot of things in training. We’re doing a lot more physical training, which the coach integrated into his sessions. We immediately understood that this was what we needed.”
