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.
This draw is one of the most balanced among others in quarter final draw. Both teams have the same level of strength and talented players. Although, Barcelona seems to be on form currently more than PSG because PSG has been on a bit of a slump lately with just two win and three draws in their last five matches in their domestic league. Barcelona has been playing very well recently and they have secured four wins and one draw in their last five matches in Laliga. I know this doesn't have much impact because most of this team approach champions league games with full energy and determination compared to how they play in their various domestic leagues.
Historically, these two teams have faced each other numerous times in champions league with a very balanced results. It would definitely be an interesting game to watch. We know PSG as an attacking team and Barcelona as possession based team, let watch out for that exciting day.
