We can't really take the performance of barcelona in UCL as a measurement of the club. I meant the competitors of barcelona in the UCL was weak teams. Barclona may get stolen by real madrid in the upcoming game. Madrid was not only coming with the different squad.
This club is also having everything to beat barcelona at this season started from a good attacking midfielder and striker at the same time. Some wingest that were coming back again after they was hibernated like vini due to the injury and many more.
I think that there's no reason to call that if barcelona will be dominating the current game. In fact, barcelona is slowly but surely was going through hard fixtures that will come soon.
Barcelona was also playing so well in UCL but it was only against weakest teams that being placed in the same time. Im still doubting barcelona at this moment. it seems like that this club will not able to beat madrid with the current suqad.
The club needs someone like lewandowski. Barcelona didn't have great attacker this time. Lewandoski was always able positioning himself better than barcfelona
If you look at Barcelona's performance in La Liga, I also doubt that Barcelona this season will be able to go far in the UCL, but currently in the group phase the Barcelona team is very lucky to be joined by a team whose quality is weaker than them so up to now there are no obstacles whatsoever for Barcelona. in the UCL match, later in the know out round it will probably be the real decider when Barcelona faces a stronger European team.
The Barcelona team under Xavi's guidance is slowly improving to become better, but when compared to the top European teams I think they are still very far behind, so it's natural that many people don't favor Barcelona in the UCL this season.
the group phase will probably be easy for Barcelona. but looking at the next phase which will bring together strong European teams, it will not be easy for Barcelona. If they meet Madrid or Man City in the last 16, it will be a loss for Barcelona. Facing a very strong team will be pressure for Xavi's team. we know the quality of Xavi's team play. they are not weak but often when facing a stronger team like Man City, Xavi cannot do anything because his strategy can be very easily known and dealt with by opponents.
