Manchester City have failed with a bumper offer for Chelsea defender David Luiz. The Sun says Chelsea have rejected Manchester City's £30million bid for David Luiz.

City boss Roberto Mancini needs defensive cover with Micah Richards crocked for 10 weeks.

Luiz was axed from last night's win over Reading while Chelsea and City tried to thrash out a deal - though the Brazilian centre-back claimed on Twitter he has a knee injury.

Chelsea were angered by the Tweet and Luiz has been fined.

Boss Roberto Di Matteo said: "This social media thing is all around us now. We'll deal with it internally."
