Lol, my apologies. The hyperbole from the anti crew has gotten me all hyperbolic myself :)
I'm kinda in your boat. Didn't even want MP to start with. Didn't want Mancini fired, not because I particularly thought he was great, but because I didn't think there are that many good coaches.
In my opinion, coaching at the top has more to do with talent and built in credibility. So, either you get someone who has won a lot like Pep and Klopp, or you get a specialist like the crazy Chilean or Van Gaal, who tend to run their players into the ground.
Mourihno used to be in the Pep/Klopp category. Now he is more like Hindink/Ancelloti. Guys who have won and people respect. But by and large, the difference is talent, not coaching. Or how else would one describr the present manager of the year, Luis Enrique?
average at 2 stops, became the coach of a bunch of extremely talented players, and suddenly he seems like a genius. Crushing everyone and everything around. This is a guy half his board wanted to fire a mere 13 months ago.
So, i generally roll my eyes on manager discussions. I think managers are constantly overrated or underrated. They are mostly all average, with some bad ones sprayed in.
So while I'm all for Pep coming, the reason why I want him is mostly for his recruitment. Sure, he'd add some gengenpressing here, some tactical nuance there. But his greatest attribute will be the talent his clout brings to the club.
So until he arrives with all the best young talent in Germany, Spain, and England I support the present coach. Especially in light of the fact that he gets it right (as in doing what 95% of coaches in his position would have done.)
Managers live and die with their stars. Pelegrini will too. And I can't fault him for that.
