Nothing is impossible, PSG still has the opportunity to win the Champions League trophy even though they have never won it. Inter Milan is certainly much more experienced than PSG, we know that the Serie A representative also has many other advantages. However, it would be wrong to underestimate PSG. Luis Enrique has a better reputation in the Champions League than Simone Inzaghi, that should also be a difference.
On the other hand, regarding last season final match between Madrid and Dortmund, I think the match was indeed unbalanced, Ancelotti has a much better squad depth than Dortmund, besides Madrid is the king of the Champions League. However, for this season final match, I think the strength of Inter Milan and PSG looks quite balanced.
It seems that I am also optimistic about PSG but still not underestimating Inter, in terms of attack power PSG will dominate because under Enrique we have seen how aggressive their attack system is. While Inter must do the same thing as when playing against Barcelona to be able to balance PSG. For me PSG and Barcelona have similarities in carrying out attacks on the opponent's defense. Fast, effective and sharp counterattacks are Enrique key, so Inter's job is to find a way to break the attack.
