Is also a strong personality. One of the best attributes of Pep (for mostly better and sometimes worse at times like with Eto'o) is his strong personality.
Koeman is more a stubborn coward than a strong personality. He targets relative no names like Puig to flex while doing nothing about carcasses like Busquets and Pjanic.
I don't dislike Koeman in terms of mentality and personality. His case is different than EV and Setien. I am willing to accept a manager getting in conflicts with players to maintain his authority in the team. It is important for the manager to be respected and obeyed. Hell, I'm a big fan of Pep and I thought he was terribly wrong with Eto'o and some others as well. It happens. 24 players in the team and you can't always please everyone.
I just think that he is not the profile we need in terms of the football we wanna play. We need somebody with a vision and philosophy who would develop the team gradually in the direction we want. Xavi is far more likely to do that than Koeman is.
His decisions on the field in games, and even before games leave a lot to be desired. I expect Barca to not be successfully pressed by a team like Eibar, or our manager to be tactically dominated by Eibar's manager.
A top manager fixes the issues in 10-15 mins. Doesn't let half a game pass by with us trying to build from the back with 3 defenders stepping on each others' toes.
