The current situation is too tough for Nice to try to disrupt PSG's dominance. Indeed, at the start of the season, we saw that they were not very good, but now they are improving gradually and starting to return to a good trend for PSG.
I think Nice can only show his best game this season. they don't have to be too ambitious to bring down PSG. do your best, if there is a chance then they will get it. otherwise, they will have to be satisfied with the final result. However, no team in Ligue 1 is a strong rival for PSG.
At the beginning of the season I thought Nice would be able to compete with PSG and stop its three seasons of dominance in the Ligue One. But I was wrong because they began to lose form which led to them losing the top spot and are now trailing the champions with five points. Sometimes I don't really blame the clubs in the French League because they don't have the financial backup which means they will not be able to afford some quality players. They don't also have a good bench, so they begin to struggle immediately after some key players are injured or suspended.
Until these clubs attract investors maybe from Qatar or Saudi Arabia, they might keep on struggling in the League. Lens would have broken the jinx last season but they lost the title with just one point. They are currently in the seventh position which is a clear proof of the inconsistency in the French League.
