Really? Do you need to sit on one team and finish fourth every season still riding high from the invincibles of how many years ago? I think Wenger is a great manager I really do especially for developing players and much of his career at arsenal the funds haven't been there when he's needed to make a push with a few big pieces. He's won lots of FA cups which is a big competition but really the third most important.
But.... Mourinho won the champions league with Porto along with a couple league titles, couple league titles with Inter and a champions league win. Both of those teams were not the best team but he had the best tactics. 3 league titles at Chelsea a few FA cups, league title at Madrid. Sorry but he's done Ok, yes he's arrogant and maybe needs to change his approach if he wants to be Manchester Uniteds manager but how can you question his success.
Same could go for Pep then no?
