It is true that Nice are waiting behind them, but they have played 1 match too much. PSG currently has 43 points, while Nice has 38 points. If PSG completes its missing match and wins, the point difference between them will increase to 8. This is not a score difference that can be easily caught. To be honest, I cannot think of any team other than PSG as the favorite for League 1 this year. They are the only team that will become champions. I'm sure Luis Enrique will lift the cup this year.
Brest also has a very good winning streak, they are in third place, although Monaco will most likely be able to move them up when they finish the missed match. As for the match with PSG, no matter how well they play now, against PSG they will have very little chance even for a draw. Enrique has returned the old confidence to the team, and it is now obvious that there is no competition for them in Ligue 1, this will be another year when PSG become champions without proper competition.
