The fact of this game is both teams came here by beating very tough teams, while some pundits and oddmakers are putting PSG a bit ahead, it's also true that we are going to see both of them have near equal chances. It's football world too, so we could see one team be very lucky with some shot, or the other team be very unlucky with theirs.
Last year, I remember very well when PSG played against Dortmund, and PSG missed so many chances that they normally wouldn't miss, they were normally much better and could have done a lot better, but when you look at the result, it didn't matter because no matter if you are unlucky or not, if you lose then you lose. So this game is open to anything, we need to watch and see who will be the winner, it's hard predicting from now.
PSG and Inter Milan are two strong teams who already have several UCL final experiences. And they should be able to overcome the atmospheric pressure of the final match. And in this case, Inter Milan is actually much more experienced. Maybe in terms of attack patterns and aggressiveness PSG's game does look slightly superior. But Inter Milan, with their solid defense and their attack line which is always able to attack with different styles, is always difficult for opponents to predict. So yes, even though the bookie may favor PSG, I'm sure many of us sometimes think otherwise. And there are also those who agree.
