its been more than 10 games for him to see it. I would have clinged on to even 1 thing he had changed to make the team better but I am yet to see it (benching Pique doesn't count). We look to be regressing every passing game and there is very little hope from what I have seen so far that Lucho has the brains to turn this trainwreak aroundSure and Lucho might realise that and switch back to a central midfield based play if he finds that the other alternatives are worse. BUT you've got to give him time to experiment and figure that out. Because, once again, Barca are in a period of transition. Infact, it would have been irresponsible of Lucho to not try out a different system and go with the already-proven-to-be-found-out central midfield focus right from the start of his tenure.
My own perspective is that Barca, with it's current players and current football climate, would benefit from an Argentina 4-4-2ish approach. I think it would be a lot more successful than the "4-3-3 the true BARCA way" midfield that a lot of people are clamoring for. Will Lucho go for it? I don't know. Will the press allow him to do it? Don't think so. Will the local fans like to give up their identity and become a more defensive oriented team? Maybe, but probably not.
But you're never going to find out if you sack managers two months in and/or do not support him fully during his tenure. What do you think would happen with the new manager if you sack Lucho? He will come in a football and political climate where he would be under immense pressure from all sides to return to Barca's roots (even though it is clearly unfeasible with the current crop) because everyone is tired of these non-Barca formation experiments. Do you really think this brings a guarantee for success in the future? Essentially you're hoping to luck out on everything coming together a la Pep.
