It's Mancini for me, he not only new how to win trophies with his teams, but more importantly he new how to have his teams defend, yes we would lose on some occasions, but we always had that look about us that we were not going to concede, right now under Pellegrini we go forward and look menacing, and we look like we can score at any time, but likewise we look like we can also concede at any time away from home, if Pellegrini can't get it right with the defence, then i can't see him being our manager for too long after the season is over, getting past the group stage in the CL is one thing, but City need to win the league to show everyone that we are as good as we think we are, after all the league is a long season, but cup games are only a few games compared to the league.
