Mourinho used a 4-4-2 in Saturday's victory over Juventus, drawing comparisons with the tactics of his predecessor. "I won at Porto and Chelsea with 4-4-2," he explained. "It's not an invention of mine or of Roberto (Mancini). The diamond midfield might be a more recent invention, but it's not new. It's a system with various interpretations, it can be black or white. I prefer by far the 4-3-3 and I am convinced that a great team that wants to play well and win has to know how to play like this, but like I said in my first press conference here, I'm not an idiot. I know how to change and assess changes according to situations and the form of my players."
