PSG certainly feels increasingly benefited by the results achieved by Monaco last night, losing to Nice meant they suffered their first defeat in Ligue 1 and made it two unpleasant results in a row, and if PSG managed to win against Marseille it would make PSG have the same point as Monaco and only have a difference of one point from Nice, especially since Brest will face a fairly tight match against Lyon and it is very possible that Brest will fail to get 3 points even though it is still very possible for them to get one point, so that these teams have points that are not much different and make this season's competition even tighter and more interesting.
PSG must not waste the opportunity to win against Marseille in the next match, Luiz Enrique must implement the right strategy so that they don't lose.
Nice has become one of the strongest team in the Ligue one so far and I believe they'll be more successful this season than the previous, they've broken Monaco's unbeaten run which makes them a threat to other teams currently because they've beaten the two strongest teams in the Ligue this season, PSG and Monaco and if you check the league table you'll see that they're currently unbeaten and has won 3 matches with 3 draws making them the most outstanding so far, I just hope they continue with this good form and not drop below the top 4 later, hopefully they're going to play in the Champions league next summer.
The defeat of Monaco has given PSG a chance to go back to the top 4 they're currently 5th in the table but if they win their next match against Marseille tomorrow they would move up above brest if they fail to win their match, but the match might be tough for PSG because Marseille are currently in form and are currently in the 4th position on the table.
