Any coach that would have inherited Messi, and the Spanish National Team core (Puyol, Xavi, Iniesta, Pique, Busquets) coming into 2008 would have had great success.

A large core of his team won the major tournaments in 2008, 2010, and 2012, when he wasn't coaching them. Plus then you get to throw Messi on that core on top of that all. Team was also successful in the seasons before he got there, and immediately after he left.

At Bayern he took over a team that won the treble, pillaged their top competitors of their top talent, and still hasn't been able to get back to the finals of the Champions League. And once again he was able to choose from pretty much the German national team who had just won a World Cup when going to select his side.

City is the easiest option because they are going to have the most $$$ to spend, they will have the lowest pressure from the fan base (United, Chelsea would both be tougher), and of the teams mentioned they have the best base line of players to start from.

Also think he avoided United and Chelsea because he didn't want the inevitable comparisons to Fergie and Mourinho that would have come with those appointments. No history or great coaches to compare him to at City.

It will be his toughest appointment yet though because he isn't going to have the ability to select from the top players in the world already at his disposal like he was at Bayern or Barca.
