Barca job not suitable for everyone, it demands a high degree of performance and should have a rigorous performance evaluation system just like top firms. If the manager does not meet the acceptable levels of performance and goals, he should be given a warning and asked for improvements. If he persists and didn't improve, he should be fired. I know what you and EV's cheerleaders would say, he won trophies. First, that's the minimum requirements for any Barca manager.
(1) We won 8 Liga titles out of 10 the past decade, so what EV did wasn't exceptional by any means.
(2) And this is only one aspect when you evaluate a Barca manager, then you have the style of play. No team in the world has a more iconic style of play than Barcelona, so when a manager comes and tweak that style, we are all fine with it, it's part of the evolution. But what EV did is transform Barca style into something we don't know, call it Mourinho style, Catenaccio (Probably you had to google it
), defensive style etc. whatever you want to call it, it's not Barcelona, it's ugly and boring.
I don't want to start with his match tactics, overly reliance on Messi, overplaying underperformers, man-management, treatment of youngsters and La Masia...etc. The list goes on and on. A high degree of performance at Barcelona require an excellence in all those important aspects, not just one aspect.
It's really not as simple as "As if he wasn't able to make a single right call." At a club like Barcelona,
(3) we demand the best, creme de la creme for any manager. We should only hire the absolute best. No room for mediocracy and Valverde farts mediocracy in every game we play.
