Nice has demonstrated stability and competitiveness to avoid relegation and even makes it to the top four in some instances. Their current improved form makes them look like a tough a top team in the league, but that hasn't enough to challenge for the title.
Despite Nice flopping a bit in their quest for the Ligue 1 title, is still applaud their consistency so far because it's not really easy to maintain such form since the season began and even maintain the second position after losing our the top position to Paris Saint German. Nice have won 10 out of 17 matches they've played so far, drew 5 and lost just 2 and has a total of 40 points so definitely they're good and one thing I admire about Nice is their solid defense as they don't concede too many goals that's why they conceded just 9 goals in their league matches this season and scored a total of 19 goals.
Actually, such a small number of conceded is certainly a good result but unfortunately, at the same time the reality is that Nice does not have a high number of goals. So ya, although Nice is in second place and 5 points different with PSG, but I think Nice is still not strong enough to be able to compete in the title race. But yes, at least with results like this it is possible for Nice to finish in the top 3 and will play in the Champions League next season, of course it will still be a good result for Nice this season.
