PSG is undoubtedly a strong team this season. They have invested a lot in this season, since they have entered the Champions League final this season, now they are eagerly excited to become champions. They have won the Copa de France trophy a few days ago, this season there can be two trophies for them if they can win the Champions League trophy. I think PSG players are much stronger than inter at the moment, so they will definitely play their best performance against Inter.
Although they have not won the Champions League trophy so far, but they were runners-up, maybe this season their history can change, and they can become champions by defeating Inter. However, it will not be so easy to beat Inter, Inter Milan has won the Champions League trophy three times before, so they also have experience. Moreover, since inter is in second position in their domestic league, they have not won any trophy this season, that is why they will try their best to win the Champions League.
They have invested a lot in every season, for some reason it didn't work for them so far. The fact that they lost Mbappe and still got better is a big deal for them, not because Mbappe was bad, I mean just because they may win it, doesn't make Mbappe the reason they are not winning, some people say that but that's wrong. They tried so much for 5+ years and always failed, and I have a sneaky feeling that they could end up losing once again too.
Because of historical reasons, whenever they end up at higher level and "win or go home" situations they ended up losing, so I am sensing that it could be the same here too. But this time they are facing a team we could all arguably say is "worse" not much, but Inter isn't better, so it could be the first time PSG wins it.
