I think Inter Milan would win but above that I have a feeling that this might just be the game that PSG has been longing for, they can finally lift a champions league trophy.
PSG would really require the best from Donnarumma in order to handle Inter Milan counter or attack which will be very dangerous because they are not just good with defending but also clinical with chances.
I think PSG is the clear favorite in this match. Even Inter reaching the final was a great achievement for them, but I don't think they can win the cup. They defend well, but their opponent has the best midfield in the world right now. PSG have been trying to get this trophy for years. After Mbappe left, they started to play a completely different game and I think it was healthier. Now they need to win this trophy, which is missing now that they are so close. I think they will get it.
PSG being the favorite to win the UEFA Champions League trophy is not a guarantee that they will beat Inter Milan in the final if they don't work hard for it. We have seen what Inter Milan did against its opponents in the knockout phase of the UEFA Champions League competition, and PSG wouldn't be an exception if they underestimated Inter Milan in the final. PSG wants to win the UEFA Champions League trophy this season so that they will be among the clubs that have won the prestigious trophy, while Inter Milan also wants to win this season's UEFA Champions League trophy to make up for the one they lost against Manchester City, so the final won't be easy because both teams.
Nothing is guaranteed until the match is played, it is okay to have favorites, especially in a fierce match between two performing teams. As much, all gamblers bets on the team they consider favorites, which gives each one a different opinion and predictions. Inter Milan will not be the ones fighting to couple their performance against PSG, it has been their pattern having perfected already, PSG seeing what happened to Barcelona, will be finding ways to adjust to become better, giving them instability in tactics while Inter Milan takes on their usual style.
Everything we've optioned so far will be cleared up by the players on that day, PSG vs Inter Milan.
