It's no longer about who is big and who is not. In fact, last season should have taught most people a lesson. For example, how many people here thought that PSG would go all the way and lift it? I am quite sure they were very few, if not, none! If you recall very well, PSG had to even go for play-off in order to qualify for the next round.
Strength or Player quality aren't always the key to a club's success, and I agree that last season, very few people believed PSG could achieve new Champions League history, but that was achieved through their hard work. It's too early to say which club is strong and which club is weak, because sometimes our predictions don't go as expected. This can be seen more clearly, so the round of 16 could be the first step to see how far the teams will go in this season's Champions League.
I agree with this point and say that Ronaldo is a star player in Al Nassr in the Saudi League, but his team is not winning the title. Again, when Ronaldo, Messi and Mbappe played together in PSG, the team could not become the champion. It can be said for sure that having a star player does not mean winning. If there is no good relationship within the team, then it is not possible to win. Those who can do the right thing at the right time on the field will be able to grab the best place. For this, not the star but everyone in the team will have to work hard and win.
From the group stage, there are weak opponents, which is why the true strength of the team cannot be understood, but the true face of the team can be light out from the round of 16.
