Manchester City boss Manuel Pellegrini has dismissed claims from Jose Mourinho of a "campaign" being waged against Chelsea.

Mourinho claimed there is a 'conspiracy' against his League leaders after Cesc Fabregas was booked for diving when his manager thought he should have been awarded a penalty in the 1-1 draw at Southampton on Sunday.

"I don't want to talk about what other managers say because I don't know what happens in every game. Maybe as a manager we only know what happens against our team. All teams have difficult moments with referees," said Pellegrini.

"All teams drop points because of referees making mistakes. The first goal by Burnley against us on Sunday was offside.

"It's normal and I don't have any doubt about the way the referees whistle every game. I trust absolutely in the way they do it."
