Corinthians president Mario Gobbi on Sunday said that striker Paolo Guerrero had been attacked by his own fans, after they invaded the club’s training center in protest of the Peruvian’s recent poor form. Gobbi said the protest eventually turned violent as the fans, which numbered close to 100, grabbed the striker by his neck. He also said that other club employees were attacked during Saturday’s confrontation. The fans eventually left the training center after a brief meeting with coach Mario Menezes. They stayed inside the club for about two hours, Gobbi said.
