All great managers but we will agree to disagree. Footy years ago was much different than it is today and today's game is significantly harder. SAF and others didn't do as much in as little time as Mou did. I know the argument already... Mourinho gets to be in big teams with big bankrolls, and I'll reply with he started his winning success at Porto for 2 years winning everything possible and many many managers have had opportunities like Mou has had at the big clubs with the big wallets and were not successful or as successful.
Mou truly is a legend in my eyes, but I'm a self confessed fanboy of his so isn't much to change my mind.
His arrogance is what pisses a lot of people off, but it's all mind games similar to what many managers do and I love it. SAF himself is arrogant and has his own mind games as well but I guess being a successful manager at Man U all these years, people give him a pass.
The only negative behind Mou is how he's bounced around a lot of clubs and leagues but I'm sure if he didn't have a problem with Abrahmavich, he'd still be at Chelsea winning.
