The only thing I'd always give credits to Van Gaal is the successful integration of players like Xavi, Puyol and Iniesta in the first team. I don't know if he was somehow obligated by the board to work with the Cantera or not, but it's a fact that these guys made their debuts with Barca's shirt under Van Gaal, so yes - credits to him about that.
And if we forget about that for a second, die bastard. Die.
And I agree that Antic shouldn't be here. He did his part-time job in the club and did it pretty well. I still feel regrets about the clash with Juve in the Champions League, though. After 1:1 in Turin in the first game, we had a pretty good advantage, but we fucked up. But Juve were more prepared for a battle like this, we were just a mess at this moment. (and it was not Antic fault)
