The thing is, City may have been doing well, but the warning signs were already there for City this season in that midfield and defensively as a team. Their away games in the Premier League, especially, have illustrated that. They are lacking the control in midfield with only 2 players in there and teams have found it easy at times to play around there and mind you, despite thrashing United in the derby, there were massive gaps in between City's defence and midfield which Rooney exploited it but to no avail thanks the rubbishness of his team that day. And yet despite all of this, Pellegrini did not look tighten things up yesterday. Also it wasn't just about the lack of mental strength and focus yesterday, the key issue was the setup. Any team playing a 4-4-2 against that Bayern team is extremely suicidal, even for a team with quality and/or with great mental strength and concentration. And again, am only focusing at the game alone yesterday. So, don't get why you are suddenly looking into other aspects of Pellegrini.
