Barcelona needs more time to win the Champions League. I don't think they can win the champions league this season. Since it is a young team, the harmony of the players will increase over time. They may be playing well for now, but their performance may not be sufficient at the Champions League level.
This is not a criterion because the victories they won in the groups were not difficult matches. There are much better teams than Barcelona and I do not give Barcelona a chance this season.
At least they can beat Munich or Manchester City as the strongest clubs in the UCL including Madrid, it is certain that it is clearly very difficult for Barcelona to overcome and get past that club, Barcelona has a lot to fix to be able to become the best club and win the UCL title again after Having failed in the UCL for so long, I think Xavi has a tough task to bring Barcelona back to shine at the UCL level.
Even though there are several talented young players, it's not enough, Barcelona still doesn't look better, just look at yesterday's El Clasico match where they still couldn't beat Madrid, who have reached class at UCL level, I think it's still too early to predict anything about Barcelona. , they have to improve a lot of their shortcomings to be able to perform even better.
