Barcelona concede a lot it is a fact, before that Barcelona conceded 4 goals from Girona, Atletico Madrid and Real Madrid, and now they conceded 5 goals from La Liga mid-table. It is clear that with such indicators can not win La Liga, because Real Madrid conceded only 15 goals, almost 2 times less.
I would not say that financially Barcelona is in a catastrophe, after all, they found money for enough quality players like Rafinha, Lewandowski and besides, they have a lot of their own pupils, who play almost on a level with their more experienced comrades.
Nevertheless, this season will definitely end Xavi's career at the club and while the club has time to find a top coach to match the club's ambitions.
It is not clear why the defensive game deteriorated so much, it seems that there were no such strong changes in the team for everything to become so bad. Barca still have financial problems and they still have debts for players with old contracts, but they are gradually being paid and I don’t think that’s the problem.
Yesterday at the post-match press conference, Xavi said that his work at the club is not properly appreciated, he is not respected and this depresses him very much, and he simply does not have the energy to continue working. There is still a lot of time until the end of the season, with this attitude it seems that the results will only get worse, so it is possible that he will leave even earlier if a replacement is found for him earlier.
The situation is ambiguous. On the one hand, it is clear that such a club as Barcelona will always have big ambitions, but the opportunities are now very modest. Last season Ter Stegen and Real's slump helped a lot, but now it's gone. Although transfers Barcelona held a decent level, but they were few, and the pupils dropped out or injured quite often, so that the problems with the composition of Xavi had, but on the other hand in the defense is really going on unknowable, there is no stable game, in the past for some reason kicked out Obameyang, although he scored and left Lewandowski, who stopped scoring. Alba, Busquets and Dembele have left, but they have not found quality replacements for them.
In general, Xavi was able to bring Barcelona to a decent level and to some extent coped with the crisis that was before his arrival, but to bring Barcelona to a new level you need other money for transfers and now a new coach, since Xavi has not succeeded to the end.
