I assune that people are giving more attention to the French side PSG because of two reasons. One day had a good season in the French League as they won almost all the domestic competitions. People are assuning that they are better. Secondly, they are getting sympathy support because they have not won the Champions League before. They are getting all the support because people want them to win the competition for the first time.
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..
