I didn't scroll through this thread very much, but I have a need to say this:
I really believe in Xavi. I think he has a very rough time implementing some of his ideas due to the financial and structural catastrophe at the Club. About playing "his friend" Busi, I really believe that Busquets has a clause in his contract that strictly says how much play time he has to have during a season (again, this is my opinion, I haven't verified it anywhere, but is it really that hard to believe in it considering kinds of contracts players signed during the Bartomeu era?) and Xavi can't do much about that. And since Busi must play, best thing for Xavi is to boost his confidence through press conferences and hope for the best (but even he knows that Busi's time has long passed). We have seen some of Xavi's ideas when he had Dani for a couple of games, his idea is that one wing back players enters the midfield middle during possession thus creating an extra player there and free the line for some of our faster players (we trashed Real Madrid 0:4 with this tactics), and I trust he has many more up his sleeve, but he demands players of certain skill and ability to try them in action.
I love slow build ups, be that during a game, or during a rebuilding of a club. I'm somewhat disappointed that the Club didn't grasp the opportunity to slowly rebuild with it's own youth academy (although I do understand that Pedri, Gavi, Ansu and Araujo would probably look for another club if this were the case), but instead chose to go for an instant success which turned out to be a fluke. In my opinion, the press would understand what the Club is going through, the fans would accept that we are out of any major title battle for a couple of those rebuilding years and most importantly, Xavi could work without any sort of pressure during that period - that way we could have stabilized the Club's finances, and have a competitive team in which we could fill voids with some of the worlds finest talent.
But since that didn't happen, we should ease the pressure from the fans, be realistic about our team and our chances in certain competitions and BE PATIENT. If Sir Alex Ferguson met this kind of pressure and backlash when he started out, he would be remembered as a fluke, but instead he received trust and was given time to prove his worth and that made him one of the best coach in history. I'm not saying Xavi will some day be recognized in that category, but we must give him time and trust to see what he can do. Since this is a new age and time to get results is way shorter than when SAF started as a coach, I would give Xavi another two years fixed, because after we clear out our dressing room, I think we have wonderful things to look forward to.
