It seems that luck is very much on Barcelona's side this season in the Champions League. Barcelona occupies the last group which is inhabited by teams that tend to be no better than them, so basically Barcelona will be the favorites to qualify for the round of 16 this season.
I know Barcelona shouldn't be happy because no one knows if they can overcome all these challenges easily. Porto and Shakhtar are not to be underestimated, but I'm sure Barcelona will go ahead as planned.

It's true that Barcelona was a little lucky this time. Because group H is not inhabited by clubs that are strong enough to beat Barcelona. But one club that will make things difficult for Barcelona is Porto. Last season Porto made many surprises. But that doesn't matter because both Barcelona and Porto have the potential to qualify for the round of 16 together.
The most difficult group in the Champions League at the moment is in group F. I think the most difficult competition is in group F.
And this season Xavi should prioritize the Champions League. Last season he only prioritized Laliga and it worked. And this season I'm sure Xavi wants to reach even higher with Barcelona, namely in the UCL.
