You need a clear identity on sporting level before even talking about a coach. Under Bartomeu we had what? 4 or 5 different sporting directors? Can't successfully work with an ever-changing basis like that. Not only sporting directors changed, but also their ideas and transfers, sometimes Bartomeu had his say in transfers. The coach was just the one who had to work with what he got. The president shouldn't have a say in transfers apart from maybe the financial part in consultation with CEO and CFO. The sporting department should get a coach which whom they closely work together and agree on the sporting direction in terms of style, physical preparation, transfers, targeted players and many other little things. Don't think that was the case and this summer the club's hands were pretty much bound. They got rid of some players who don't really fit but a major makeover wasn't possible. Finances were a part of that and that 25% reinvesting-rule of La Liga made it even harder. When I look at that posted link above that Cruyff, Alemany and Planes prefer Martinez I gotta ask myself the question if Laporta and the sporting department really want the same?! Not gonna talk about Barca DNA and all that bullshit, but Martinez' football doesn't strike me as the one Laporta wants to see.
Imo you don't have to be the most successful coach in the past to be successful at Barca. Lucho for instance had issues and showed red flags at Roma. Hard to draw a conclusion of his stint at Celta as they don't compete for the title and are a smaller club than both Barca and Roma. Lucho had his issues here too, but he was successful and imo unlucky not to win the CL for a second time. Of course he was blessed to have prime MSN in his squad, but he also had the same idea of football as the sporting direction: this was not 1on1 a copy of Pep, which he obviously wasn't, but the idea of playing offensive attacking football. Koeman plays 4 or 5 attackers when he desperately needs a goal, but does he really comes across as an offensive-minded manager? For me, no. Same accounts to Martinez. I know, Belgium is winning by some goals difference more than once, but national team football is very different to club football and he doesn't come across as the type of coach that plays the kind of football Laporta wants to see.
I want to throw in a name many will say is worse than all the coaches we had in recent past, but imo his idea of football is much more fitting to what Laporta and Cules prefer: Andr? Villas-Boas
