Pep is a great motivator I give you that, those players were obviously low on confidence and Pep gave them the push. Pep didn't buy much players when he got there, he just got rid of the rotten apples (Ronaldinho) and installed a winning mentality.
That doesn't mean he's better than Mourinho who's capable of doing the same and is superior when it comes to tactical preparation of games.
Pep isn't really good in transfers, which makes you assume that a) he doesn't know what his teams need or b) he can't judge players properly and according to his team's play.
Arsenal's squad is cack I know

, ours is underachieving as fuck and it's too old now. of those you mentioned, Terry, Lampard and Cole have two seasons more, tops. Then they're gone. The fact that they're not able to maintain top form during the course of a whole season anymore goes without saying.
And you forgot Čech >> Chezny
Btw, how do you feel about feeling RVP? I think you should do it, not because I'm a Chelsea fan but because I think he won't be able to replicate this season he just had, is extremely injury prone and nearly 30.
