They eliminated Barcelona, who were very good, what else could they have done. PSG cancelled Inter's game in the final, I didn't expect that to happen either, but if this game was played again, maybe the result would have been different.
I would say also that if PSG played again vs Inter Milan then we might see a draw then penalties will rule which team will win, and we might see Inter Milan lifting the cup. The problem with Inter Milan is its stability during successive games. I mean in Serie A they were successful and I recall even Lukaku in Napoli said that Inter is the favorite to win the scudetto. Fast forward, Inter miss many points and Napoli was victorious by a slim margin. Same in UEFA Champions League, Inter made great job after eliminating Barcelona, which was the most favorite at that time, then lost badly against PSG. The problem is the stability of the team.
