He has good and bad games for OM. Same old, same old. Thauvin has been way way way better.
Nice isn't going to finish 3rd this year. I'll wait for the end of the mercato to make predictions but you can bet PSG is #1, and after that Lyon, Lille, Monaco, OM will round up the top 5, the order being a question mark.
If Monaco loses Mbappe, Lemar and Fabinho in the next two weeks, then, they could fall out of the top 5. Lille will surprise. Maybe finish top 3. While playing the most spectacular football. Lyon will be fun offensively, but still shaky defensively (change of coach might modify that). Fekir could have a big comeback season. OM will be dangerous, but have a lack of depth after the very good starting XI, especially if they sell Cabella (as I 've heard).
