Actually, both teams have good strength. Mbappe is an important trump card and I am sure they will use this trump card in the most correct way. For Enrique, Barcelona is a familiar team. He will analyze them well and find their shortcomings. Also, PSG's defense will have a lot of work to do in this match. They have to not give too many positions to Barcelona. I believe the French can pass the tour. Mbappe sometimes puts on a one-man show and helps the team rise to the next level. If such a day happens, it could be a terrible match for Barça.
The quarter-finals is a new thing for both clubs where even though in history Barcelona and PSG do have a good history and experience, but the quarter-finals this time is a new thing for both clubs.
PSG in the previous 2 seasons could not go further and only reached the round of 16 and Barcelona is certainly worse because in the last 2 seasons they have always been eliminated in the group phase.
Now that they are in the quarterfinals, it is a new thing where they have to make a good contribution to avoid being eliminated.
Mbappe is still a good ace for PSG but other than that, there are also some players who can provide a different thing here where there are Dembele and Asensio who must have known Barcelona in terms of play and performance besides, this is a momentum for Enrique because this is the first time they meet (Enrique and Barcelona) after they separated before.
