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.
