Well, I do support PSG, perhaps because of the good season they had in the French League, but that's no real difference as they've always won their league for years. Their stats across the UEFA Champions League knockout stage are actually better than Inter Milan's, and overall, statistically, PSG is better when they are both compared, imo..
They always win their league Ligue 1 which is something they have done for many years. You made good point that PSG stats in Champions League knockout games are better than Inter Milan. Inter Milan has won Champions League three times before but PSG has been strong recently even getting to final in 2020. While past records might show PSG ahead in friendly games these do not always reflect how they play in important matches. At end numbers can tell us something but how team plays on day of big game like Champions League is what truly matters.
I don't know exactly about what stats you guys are talking about but Inter managed to win in Munich and draw in Barcelona, not too many teams would be able to do something like that. PSG have beaten Liverpool at the penalty kicks, than Aston Villa, which are a good team but no more than that, and yes, they did well against Arsenal. I am more impressed with a team that beats Bayern Munich and Barcelona rather than Liverpool and Arsenal.
That's were the problem lies, you are judging based on big names without considering the current form of the teams and not their previous achievements. Remember PSG beat Liverpool at Anfield in regulation time before the added extra 30 minutes which Liverpool couldn't score in their home. PSG knocked out 3 premier league teams on a stretch, something I don't see inter Milan doing. Shutting out Liverpool and Arsenal attacks from scoring in both matches played in England is no small job. Try to see the extent of what PSG did before getting to the final, then you will realise that they are not a team to be underrated in this final. As far as this final is concerned, I will remain neutral because both teams deserves the trophy. But trying to think that PSG got it easier on their way to the final is what I don't agree to.
