i think inter will win mainly because of PSG 's weak defense and inter being good overall.

There's a lot of advantages they both have; one way or the other, they have something that would convince me that they both won't misuse an opportunity if it shows up cheaply, like it did to Tottenham against man United. Being too prepared for something can build serious over-confidence -- may have been delevoped for good, but the after effects would be simple mistakes and reluctance.

Inter winning the UEFA Champions League would make Serie A much stronger, and bring more exposure towards the league.
