The knock on Cuper is that he is succesful while playing an ugly brand of football. And at times it can be REALLY ugly; painful to watch even.
he's known for beeing an eternal second, but thats *#*#*#*# , he's good but his game style (at least with inter did) sucks. Too defensive even for Serie A ...i said all add the fact that apparently he doesn't like stars...after Ronaldo , Crespo told that he went to Chelsee cos Cuper didnt find him usefull for his game (he even said that if Cuper left like 1 month and an half ago he would still be with inter)
