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.
Inter is way on the different level. They beat the winners of La Liga and Bundesliga that can't be compared with PSG, which was beating the weaker teams than them. So, it totally makes sense to argue Inter is clearly a bit better, though the odds said the opposite. It only reminds me with Europa League final when Tottenham gets bigger odds, but win its first european trophy.
Yea, Inter is a strong team and has proven that after trashing the giants of other leagues on their way to the finals. PSG kicked Liverpool and Arsenal out from the Champions League but I still don't see PSG capable of winning Inter. Inter has a good defense and sharp attack, they can score as many goal as possible but PSG finds it difficult to score more than one goal this season in UCL.
