Hence the reason Mancini is fighting for his job. If it was all about money then Mancini would have won the league by now.
You do realise City is a bad example because they're the second side who have acted like they have bottom less pockets? There's Chelsea as well, which of course means they don't necessarily have
more money than the rest of the competition. Give it a season and Liverpool too will be making very expensive signings so make that three.
You've also negated to appreciate the time it takes to put together a squad. City aren't Chelsea with a ready assembled one, one that would have won the league with Ranieri had it not been for the Arsenal invincibles season. The Mancs were a lower to mid table side at best before hand.
City aren't in the Champions League (yet). Give it a few seasons and they will win trophies as they can start to attract players (remember Kaka?).
But the point I've carried all the way through is in bold.
Money will never = success.
You need money to be successful though.
Bingo, and for every club that Mourhino has been at and won, there has been more money than the competition.
It's no surprise too that if you look at the clubs he's been at, bar Chelsea, they won trophies recently before his tenures - and continued to do so afterwards.
As said, a good manager, but his best ability is knowing when/where to go.
If he returned to England and won with United, against City, Chelsea (and Liverpool?) it'd be impressive as that doesn't completely fit with his history of Chelsea, Inter - maybe Porto and we'll see about Real. But if he returned to England and won with Arsenal, I'd eat my hat.
