It's actually too early to say who the winner of this UCL final will be. I completely agree with you about Inter winning. But we must also remember that before competing in the final, both teams still have other fixtures in the domestic league and if Inter or PSG lose a player to injury, it will be a big problem. It would be better to see if both teams have any problems with their players.
Not too early though 😁, There are only 2 teams left. Inter Milan has loads of experience and they will use that against PSG who have a number of youngsters. There is also a factor of pedigree. PSG is seeking the first UCL VS a team that has been there before, the former will certainly have a lot of pressure to win the match. So to me Inter Milan has a higher chance of lifting the trophy.
