It seems like a good decision to go for betting on Nice for this match. Because I think regardless of their recent performance we saw in French Lweague they are a team at the top of the table and they can have a much better and higher chance to win this game easily against Lyon. We can't forget Lyon was a team at the bottom of the table and they are even losing games against the weaker teams and I think even in the best form for Lyon, they can't beat Nice at all.
I agree with you, however Nice statistics show that they are more consistent than Lyon. Ambition to compete closely with PSG is already too late, their chances of winning a trophy are very low considering the point difference that has already formed. Beating Lyon and securing full points can reduce the gap with PSG, but the fact is that currently Nice is 1-0 behind Lyon. There is still a chance to turn things around, although it won't be easy.
The first half has finished, and Nice must maximize the second half to secure full points, Lyon seems to be starting to show a revival. Lyon ambition to get 3 points is very reasonable, they need it to stay away from the dgradation zone. If Nice fails, it means that their performance is indeed declining, and Monaco has a big opportunity to overtake their position.
There is still one more half to get things going for Nice, and Lyon will likely play defensively to maintain their lead. The statistics in the first half in terms of ball possession were not much different, but Nice still led in terms of shots on goal.
