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.
Bookies by the way are not so unambiguous look at PSG as a favorite and give on the victory of PSG odds of 2.3, which is certainly better than on Inter, which is given 3.5, but we can not say that PSG is an unequivocal favorite.
PSG without Mbappe plays as a real team, in which there are no players who do not work in defense and you can see that Luis Enrique put PSG team soccer and now in the team almost everyone can scoring from defenders to forwards, which makes PSG an extremely dangerous opponent.
Inter's squad is probably weaker than PSG's, but the players are more experienced and most of the leading players are aged 30+, which can be both an advantage for such an important match and a disadvantage, especially if PSG manage to score a quick goal and Inter have to come back.
