Chelsea manager, Maurizio Sarri has blamed his players after side suffered a 2-0 loss to Everton in the Premier League on Sunday.
Goals from Rcharlison and Gylfi Sigurdsson sealed the game for Everton at Goodison Park.
During an interview after the game, Sarri questioned his players’ mentality and not his tactics.
Asked why Chelsea lost, Sarri told Sky Sports: “I don’t know. The player don’t know what happened. At the moment I don’t really explain the change.
“We played in my opinion the best first half of the season. We could have scored four or five times. Suddenly we stopped to play. It’s very strange.
“We stopped to defend, to counter-attack, to everything. We had only to continue, I think. We were in control of the match.
“We played very well and needed to continue. at the beginning of the second half we didn’t play. It’s strange. I cannot understand.
“Tactically, if you don’t play, you don’t play. We changed the system but it was the same. It’s very difficult but I think the problem was mental. If you have a mental problem suddenly on the pitch, the system, the tactics is not enough.”
