The Blues have lost two of their last three games and the Italian faces his toughest test yet against the Premier League champions on Saturday
Maurizio Sarri admits his Chelsea players have a problem with their mentality amid his team’s dramatic slump in form.
Two defeats in their last three games, including a 2-1 defeat at Wolves on Wednesday, have seen the Blues fall ten points behind league-leaders Manchester City, who they welcome to Stamford Bridge on Saturday live on talkSPORT.
And while Sarri says he knew it would be difficult imposing his philosophy on Chelsea, he knows it won’t get any easier when the Premier League champions visit.
Sarri said: “I knew very well that sooner or later we have to face difficulties. When you change the way of playing, the way of football, you need to change the mentality.
“You need to change the mentality in 25 minds, so it’s not a short way. It’s very difficult.”
Pep Guardiola’s City have won 13 of their Premier League games and are unbeaten since April.
Sarri, who has experienced defeat to Guardiola with both Napoli and Chelsea – the latter in August’s Community Shield – was asked how his side can beat City.
He added: “I don’t know. Against Guardiola I lost every match, so I don’t know. You have to ask somebody else.”
The Chelsea boss reported no serious injuries ahead of the clash and is expected to restore his first-choice line-up after Wednesday’s loss at Wolves.
