I dont really see why people think its an odd choice. Football is moving on, managers aren't judged exclusively on their results anymore. A decade ago Vinnie would have been slaughtered for not changing his approach when it was clear the players he had just couldn't do what he wanted from them to a high enough level to survive but now if you want the big jobs, Its more important to stick with your principles so the bigger sides can see how you'd fit with better players.
theres also the pep factor. everybody wants pep football, they cant get pep so they look for pep influenced football which means looking at anybody thats been in contact with Pep. the clamour for it is bordering on cult-like, the entire football world wants Pep.
Brilliant to see city using Bayern Munich as the proving grounds for our future managers. If he's a success there we know we can get him whenever the time is right, if not we know he either needs more experience or he's not quite got it and we dont have to go through the pain of finding that out first hand and having to sack a city hero. It's win-win for us.
