In the previous season, Barcelona failed in the group phase because they were unable to compete with Bayern Munich and Inter Milan. I don't think that's happening again with them this season. At least it can reach the semifinals or more.
don`t be too hard on Xavi, he went the extra mile. He was playing in a group full of big teams and couldn`t do better than he did. Xavi got many things wrong, I agree with you. It must be understood that it was also the first year.
Xavi was able to finish the season well in La Liga, but he failed to do so in the Champions League. Perhaps he has little experience in such competitions so far and it is easier for him to focus on one thing at a time. I think that in the current Champions League season Barcelona will not achieve great results again, because the competition is very big.
