this season Xavi should be lucky enough not to be in the hell group. I think getting through the group phase is quite easy for Barca, they are the favorites to qualify. especially with the player material that Xavi has in the current Barca squad. of course, even City should consider Barca. unlike last season, Xavi failed, but they won't repeat that this season.
Xavi has prepared everything well, as well as his request to the club to bring in several important players at this time. I think those who have just been brought in by Barca will help the team in the Champions League.
Yes, Barcelona is lucky enough to be in the same group as Royal Antwerp, Porto and Shakhtar Donetsk, ideally they will get through the group phase easily, but the reality is that we don't know whether Barcelona can get through easily or not.
September 20 they will have their first UCL match and face Royal Antwerp, playing at home will certainly be the basis of their motivation, 3 points are in sight it seems.
