The Daily Star says his temper boiled over in the dressing room at the end.
The hot-headed Italian laid into his stars afterwards, labelling them cowards in a blast that will cause an even bigger rift between him and his players.
A club source said: “The manager doesn’t always talk to the players after a defeat but this time he decided to let rip.
"He told them in no uncertain terms that he was angry and disappointed.
"Roberto addressed all the players involved in the Everton game and called them yellow, gutless and bland.
“He didn’t see enough desire out there on the pitch and couldn’t believe we hadn’t created more chances against 10 men."
