Xabi Alonso must try to moderate the team and make the group more cohesive, with the team he has he can certainly do very well and decide to impose himself both in the league and in the Champions League calmly, he just has to work with his players, He would do well to make a retreat and talk to them
I do agree that Xabi has to make the team chemistry work better. As long as this team plays the tactic well enough, like learn how they should play, and have a good chemistry, they can't make any changes to worse, they are going to be great.
I understand it may not feel that way looking at the CWC games, but it is still the best and we should focus on that part. Because this squad, failing, and twice in a row as well, is not something I can expect. Barcelona looks prime to lose this season, they already won, so maybe this season we will reverse that. Obviously it is not an easy task, but we should consider how we can change this and have a much better result. Spending this much time on this many things isn't really that easy.
