Actually i think it was stingray who said agenda, my bad. But the point is still valid, you have used Mata as an excuse for Lampard not playing well and others like Torres and Oscar also not doing well. Like i said before the game, Mata deserved to play after doing well against Arsenal, but it's Mourinho's fault for playing Oscar out wide, because in his mind Oscar has the divine right to start and finish every game, regardless of performance. Mata alone in the team didn't result in this performance. The team selection as a whole did, and players who were preferred like Cole, Lampard and Torres were terrible to put it nicely.
