I have alwyas thought he is extremely overvalued because the Barcelona side he managed could be managed by myself with similar success. They are just the generation of our lifetime and play together since early age, at least most of them. Look at Frank Rijkard, his Barcelona team were outrageous but he has failed everywhere ever since...Luis Enrique was just mediocre in Roma and in Spain but now looks like the greatest manager in the world.
He is a real perfectionist,ok, I am afraid of that but some of the decisions he took as a Barcelona and Bayern coach were a complete joke, The game he lost against Barca with Bayern, when he played with three defenders marking Suarez, Messi and Neymar was just pathetic, every other coach would be sacked for that game only. They year before he was completely outplayed by Ancelotti's counter attacking Real, they just destoyed them, and he was again outplayed by Simeone (if it was not for pure luck in the second game against Juve they would not be there at all, nevermind they thrashed them in the first game...). In his last year as a Barca coach, when he played Fabregas as a false 9 and Messi behind him was one of the most astonishing use of personnel I have ever seen and I am sure even Van Gaal would look at that with bewilderment. Basically with Bayern he had 5-6 imortant games in his stint and lost most of them apart from Juve and was tactically outplayed in every single one of them. I am not overestimating my abilities but I think that I would be able to make that Bayern team German champions in the last 3 years.
I really hope, I am right on him but I really do not like him and have never liked his tactics. He has made some huge tactical blunders and I hope he will continue to do so.
