Chelsea management are disappointed with the form of David Luiz.
The Daily Mail says Mourinho selected Luiz to start in the defeat at Everton, but he was blamed for poor positioning for their winner.
Although Luiz indicated that he wanted to play, it has emerged he was jet-lagged following his return from international duty with Brazil. There is a concern at Chelsea as to why his performances dip for his club despite often impressing for his country.
