I never said Chelsea don't need Fabregas, I just find it funny how a Chelsea fan is saying we don't need Fabregas (fair enough) when the main reason they bought Salah and Willian was to stop other clubs from strengthening.
For Mourinho to get the best out of Cesc he would have to build the team around him and allow him to do whatever the **** he wants like how Wenger utilized him in his Arsenal days. I don't think Mourinho is prepared to do that, and I don't know how useful he would be against parked buses if he doesn't change his overall style of play.
