Monaco and Nice do have a much bigger chance because they will face much weaker opponents, but that doesn't mean it's easy because sometimes facing relegation zone teams also provides difficult resistance, because they are also struggling to get out of the relegation zone. Monaco must maintain their victory in the next few matches if they don't want their position to be taken over by challengers below them.
Apart from PSG, there is currently no team that has managed to secure their position to qualify for the Champions League next season, Brest, Monaco, Lille, Nice and even Lens still have a great chance to be able to win the remaining Champions League tickets at this time, with 8 matches left it is certain that all teams still have a great chance to be able to knock each other down in the Ligue 1 standings.
Even Brest and Monaco at the moment I think they could lose their positions if they continue to experience negative results like what happened in their last two matches, besides that there are still meetings between teams in the top 4 in the remaining matches it will present tough competition at the moment, and I am sure if these four teams will try hard to get the highest possible position in Ligue 1 to be able to play In European competition next season, I think not only Monaco and Nice have a great chance, if you look at the schedule of the four teams I mentioned, I personally doubt Monaco Nice will easily be in the Champions League zone next season because anyway in the remaining 9 weeks we will see the 4 teams will kill each other later to claim 2 Champions League tickets and 1 Champions League qualification ticket next season.
Lens is one of the teams that successfully won a UCL ticket last season and is currently starting to improve on its previous shortcomings and is slowly improving its performance by adding several points to continue to climb to the next ranking.
It is indeed very difficult to predict who will succeed in winning a ticket to the prestigious competition because the point difference is very close, while the remaining 9 matches are the same as the remaining 27 points that can be achieved by all teams and this means that the successful team has a very close point difference a chance to finish in a more decent ranking.
however, I still believe that Monaco this season can at least get a ticket to the UCL or a qualifying ticket for the european league and for Brest I need to see the next match because I see Brest has lost control a little recently.
