PSG winning by a huge scoreline against a team that people just have not even heard the name of is honestly not an achievement for PSG in my opinion. And I absolutely agree with you @hahay that they were not a worthy opponent for PSG. I don't think this win actually means anything to anyone. Of course, the loss for the opponent was absolutely humongous. But I don't think PSG should actually be proud of anything that they have achieved from this match. Because we don't see this performance from them in the Champions League. And even they will agree that the Champions League is the competition that they actually care about the most.
Revel is not a strong club, its name has never been heard of by football fans before. The big victory over Revel does not mean anything for PSG, the strength of the club led by Luis Enrique has not been able to be matched by clubs playing in the Ligue 1 caste, let alone a club like Revel that has never been heard of before. In Ligue 1 PSG is the king, no club has been able to stop it from winning the Ligue 1 title for the last few years, PSG will also dominate the Coupe de France with all its advantages. What PSG has just achieved is not very impressive for anyone, this victory is very natural for PSG because Revel is a very weak team.
