I agree with what you said. No one had ever heard of Revel, except maybe the French. So it's not surprising if they were able to win that match. I think it would be surprising if they lost or won 1-0 against Revel. However, I still appreciate what PSG did because getting a big win means that PSG still has a squad that is strong enough to be able to dominate the league. I'm confused why they didn't field a second tier player against Revel?
I don't even see such victory as such that should be exciting or make PSG it was naturally expected of them to win that match without stress which of course they did won with such a landslide victory and a very good margin such that their opponent wasn't able to score a goal against them all through the match.
Revel is a name I heard for the first time when they had the encounter with PSG, before then I never came across such name in football and of course they aren't rated any high in any of the french league they can't even be compared to any team in the Ligue 1 aswell so definitely they were no competition for PSG. In the Ligue 1 PSG remains the most elite team and have got the best squad in the french league so it was very possible that such an elite had such win or even more of such a weak team.
