Maurizio Sarri encouraged Chelsea fans to create a positive atmosphere during Wednesday's clash with Brighton and Hove Albion, claiming criticism of his coaching harms the team.
Blues supporters were vocal with their frustrations during a 2-1 win at Cardiff City on Sunday, with several fans chanting for Sarri to be sacked as they trailed in the closing stages.
The Bluebirds outplayed the visitors for large portions of the match and there was more than a touch of controversy about Cesar Azpilicueta's equaliser, which replays showed he scored from an offside position.
