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.

Barcelona are the favourite in this group, they have good players that can make them obtain victory in every match If really they want victory and Barcelona already has a good coach that is experienced. I don't think Barcelona games in this group will be difficult for them, this is a group Barcelona expected to win all their games. Barcelona can do well on champions league this time around, they just need to increase their motivation to win more.
Barcelona is indeed very lucky to be in group H, because in this group it seems that Barcelona has very good match quality. I'm sure Barcelona will lead Group H, because from a game point of view it's clear that Barcelona will beat them quite easily. Even so, Barcelona cannot underestimate their opponent, of course they also have a very mature strategy in dealing with Barcelona. Therefore, the entire Barcelona team must really bring out their full power to crush all opponents in this group or opponents from other groups.
Barcelona was drawn in to a group that they're very likely to qualify to the knockout stages of the 2023/24 UEFA Champions League competition and I think the club manager will be very happy with the draw.
That being said, Barcelona must not underrate any of the teams that was drawn alongside with them if they really want to make it out of that group. They were ousted in the group stages of the competition last season but with this season group stage draw, Barcelona are gonna play in the knockout stage.
