It was not an easy victory, PSG managed to score only in extra time, but it was deserved, PSG played better. However, what is surprising here, they have not had a worthy opponent in Ligue 1 for a long time, with varying success several teams are trying to compete with them, but it is obvious that it is very difficult for them to do so. Winning Ligue 1 and the French Cup is what PSG must do.
At the domestic level, many would agree that PSG are the main rulers, so far no team has been able to stop their progress, the trophy they just won can explain it all. PSG also seems to be able to lock the Ligue 1 trophy faster this season, Marseille and AS Monaco who were expected to put pressure on look unable to do so, they have fallen far behind. Without strong competition, PSG will always be the ruler without having to try very hard, which is also believed by many to be the reason why they often struggle when competing in the Champions League.
As long as financials seems this different, no team will have a chance to beat PSG to be fair. The gap between how rich PSG is, and how other teams look, is pretty obvious when you look at how much they are spending each season. It not even just about how much they can spend on transfers, that's great and all but it's also about the fact that PSG can pay much more in salary as well, so that's an important part, and I am pretty sure that is going to be a tough thing for all of the other teams.
When you calculate all these financial differences, you will end up seeing how PSG will easily beat everyone at France, and the only problem they have is that they are incapable of winning the UCL, which has been a tough task for them.
