Mourinho just produces dull football. Players can hit peak form because players do that, they can have amazing games because his teams are full of world class expensive players. But throughout his tenure at basically every single club the football gets worse and worse, predictable, boring and generally attempts anti-football in the 'big' games. Can't stand Mourinho's teams, I'll still be surprised if he manages to make an exciting, successful Utd team. Win a cup with anti football, sure, improve compared to previous seasons with better and more expensive players, sure, but create a great side... I'll be shocked if that happens.
