Well, that's only one part of it. The mind games that is. And the season still has some way to go.
I'm really hoping that United nick the title this year, especially on goal difference only, just to wind Mourinho up.

But seriously, i think it's more to do with the fact that Chelsea changed their set-up to accomodate two big names, plus teams have more experience holding them back than with Mourinho losing mind games. If it really were the case, then Wenger should be clinically insane now shouldn't he?
