If Barcelona become insistent on playing the same game in the Champions League it is really difficult to put them among the biggest title contenders next time. Because they still can't even get past the group stage. In the last season they could have done this by at least leaving Inter behind. But it is clear that something needs to change immediately.
Xavi played with this system in his player career for so many years of course. I understand why he insists on this game logic. But it is clear that it doesn't work in the CL while it does in the La Liga. Barcelona have really skilled youngsters and a great striker like Lewandowski.
With some additions to the team in the transfer window and some adjustments in the game strategies they should be more competitive in the CL.
As long as Xavi is the head coach of Barcelona I am sure that Barcelona will not be able to go any farther in the Champions League because after all, even though Barcelona did win the La Liga title but in reality it was just that. Due to the fact, Barcelona also failed in the Copa del Rey and thus, Barcelona does not have a good chance in the Champions League. If for example in the previous season Barcelona could still reach the quarter-finals or semi-finals in the Champions League, then this achievement could be improved this season but the fact is, Barcelona could not achieve that in its last two seasons in the Champions League.
As long as Barcelona cannot clear the problem of financial troubles, they are not going to be able to bring in the players that the coach actually wants. And if they do not bring in the players that he wants, he is not going to be able to bring in the performance that everyone wants. I would not say that he failed to achieve such and such. Because the main priority was La Liga. And that thing is what they had made a target, Barcelona actually achieved. It will be interesting to see how Barcelona is going to perform in the Champions League. It is sure that they will need new players because with this squad Champions League is not winnable.
