There is no reason to underestimate PSG. because PSG is a very strong team and PSG has a lot of records to win the Paris league, and also other leagues. It is true that PSG has no records in the Champions League as a champion recently, but they are playing very well and professional way, so I have an expectation from PSG to become champions in this Champions League season. One of the advantages for PSG is that they will play on their home ground. So PSG has a better chance of winning the Champions League trophy this season.
I think almost all Parisians hope that PSG can win their first title in the Champions League and write new history for the club. They have sacrificed quite a lot in material and energy to win it, but so far they don't have much chance of being in the final. This season PSG managed to qualify for the final after crushing all their tough opponents in the knockout rounds, so I wouldn't underestimate them even though Inter are the more experienced team because of their three titles.
Inter is considered experienced on behalf of a club that has previously won 3 Champions League titles, while the average player in their current squad has never experienced how great it is to lift a Champions League title. Benjamin Pavard experienced it when playing with Bayern Munich in the 2019-2020 season, while only Marko Arnautovic won it with Inter Milan in the 2009-2010 season.
