PSG are on track to set an unbeaten record throughout the season, I assume Luis Enrique will be able to make it happen. So far no team has been able to beat PSG in Ligue 1, so it is likely that they will be able to record the record. After successfully securing the Ligue 1 trophy, PSG focus is currently on the Champions League, but I don't think Luis Enrique will ignore the remaining matches in the domestic competition just like that.
Without the motivation and ambition to set an unbeaten record in Ligue 1, betting on PSG winning in the future is certainly very risky. Luis Enrique will certainly rotate his main squad more often with second string players, in order to give key players time to rest and use their energy in the much more important Champions League matches.
After doing a quick research, I saw there was really no team being able to finish a season unbeaten in the Ligue 1 history.

It is too easy for them unless they get complacent. Because literally nobody is near their level this season. This is their best season in a long time period...
Their remaining league fixture is also quite easy by the way.
