The funniest part is that English people claimed that Premier League was the toughest league in the world and plenty of great teams there, unlike other leagues where there are just one or two good teams.
Well, the reality was seen this season where PSG beat three different premier league teams to get here. They beat the champions of Premier league Liverpool, they beat the second place Arsenal (so not like 10th or whatever), and they beat 6th place Aston Villa (albeit that was the easiest one).
So as we can see PSG, representing Ligue 1, has shown the world that ligue 1 isn't that bad and they can beat any team from Premier league, and they did it this season. I am sure that we are going to see them play wonderful at the final game as well.
Yes, PSG has represented the French league very well this season but that doesn’t mean that the French league has become better than the English league because they defeated English teams but note that there were four English teams that made it that far in the Champions League and PSG were the only side that made such impressive results in the UCL so I can say that the English league is still better.
