It's ridiculous how you imply getting the players in shape and adding discipline to the squad is something minor. If he manages that in the world's best team that's already more than almost all coaches could do here and certainly more than his 2 predecessors did. Even Pep said towards the end of his tenure he couldn't convey his ideas to the squad anymore.
As for "Lucho had better players than Tata", I'm sorry but wasn't Tata the one who said we don't need a CB because Puyol is like a new signing? It's laughable how some of you understate the role of the staff in signing the correct players. Rakitic, Bravo & Mathieu were actively pursued and wanted by Lucho and his staff and proved to be great signings, and Arda & Vidal will hopefully prove the same. Meanwhile Pep's transfers were mostly garbage & Tata was happy with Neymar and Puyol.
"Revolutionary" and "innovative" hasn't proven to be very successful for Pep at Bayern now has it? And about Pep's abilities as a tactician, I'd rather not talk. The guy has been playing with exactly 1 system from the beginning of his coaching career. When it works, it's fantastic, but when it doesn't, his players embarrass themselves. Lucho brought a new, more direct and obviously more successful playing style too & apart from that, he reinvigorated the squad. Neymar played 10 times better this season than the last one. Suarez immediately found his way into the team (like the other signings). Messi was much better; Alves, Piqué, Busquets, Xavi, Alba & Mascherano too - some of which most people on here had already given up hope. Did Messi not only himself magically and without any influence from the coach play a lot better but also somehow make everyone else play better? Did Messi make the opponents have 0 shots on target in games where they would previously have several?
I'd advise everyone to take a moment and appreciate what we have achieved; and especially to stop thinking this is Football Manager. Some of the comments on here already remind me of last season when people came up with borderline insane suggestions like Oscar Garcia who in his entire career has only coached teams where even I could play. Shows how spoiled but also how deluded some members of this forum are. If Barçaforum had a say in how the club is run we wouldn't even get into CL and Messi & every other half decent player would not hesitate to leave.
And all of this drama because of a meaningless loss in a competition almost no one cares about... but Barça fans do because they want to impress people on Twitter... get a freaking grip.
