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That is no longer valid in my opinion, the match in the final will be different, as happened in the Europa League even though if we look at the overall statistics since the beginning Man United was better but in fact they lost in the final match as well as for the Champion League final match later between Inter Milan v PSG and if we look at the overall strength of the two teams now I think it is quite balanced so that both teams have the same chance of winning the title and regarding predictions and also everyone's favorites are different and that's natural.
