I don't know what it is, but Roma are always great in CM. In the two seasons I have played, they have both times won Serie A, reached the semis and final of CL and I think won Coppa and SuperCoppa Italia. They are almost impossible to beat, and the players they have are far better than the rest, much better than in reality, of course.
Is this an exception, or is CM simly messed up(I bet it is)?
