PSG without Mbappe would be interesting too, it's like they have zero chance to win against Barcelona.
The thing that Barcelona is most afraid of is the presence of Mbappe and that is a fact that cannot be avoided. Xavi will definitely ask Araujo to guard him closely and to stop him doesn't just need one player and it will be more than just that. Mbappe is still a frightening specter because apart from being fast, his finishing is great and Ter Stegen definitely has to be able to read the direction of his shot correctly so that it is not easily broken through.
It is clear that Mbappe is very dangerous for the opposing defense, because Mbappe also has great individual skills that guarantee a goal for the PSG team. But a tleast, if Barcelona can maximize the attack line to score lots of goals and maximize the defense line to stop Mbappe then yes, at least there is still a chance for Barcelona to win too. Because, atleast at this moment PSG and Barcelona still seem to have qualities that are not much different and as such, I think thismatch will be quite balanced so it will be difficult to determine the winning team in this match . Because after all, if Barcelona can play well then at least Barcelona has a chance to win but unfortunately, Barcelona also sometimes plays badly so it is difficult to score goals and if that happens in this match it will make Barcelona lose.
PSG has always been one of the strong candidates to win the Champions League but they have repeatedly failed. But of course, by spending quite a bit of money to develop the squad, there will be times when this team will be like Manchester City in winning its first title in the Champions League. However, I am quite doubtful that PSG can do it again this season considering that there are still quite a lot of other tough opponents and the most important thing is that they have to get rid of Barcelona first before determining their next step.
