Olympique Marseille is ranked second on the Ligue One table, they're competing with Monaco who's sitting at the first position. Checking out I didn't see PSG in the crucial positions, moreover it's very early to start concluding on the club's that would be in the race to fight for the domestic league title. I'm believing Paris Saint Germain will always make good path to the first position, furthermore the team's healing after important players exits the team, it's definitely going to affect their performance a little bit, but the new boss, Luis Enrique will make sure he strengthen and enchance the team.
It is indeed Luis Enrique's main task to make the PSG team successful again this season even though PSG only has one more star player on their front line. Slowly PSG will continue to create competition again in Ligue1 in order to be in a better place even though Marseille and Monaco have also shown their good performances at the start of this season, but these two teams still have to be wary of PSG because PSG can still make greater dominance in Ligue1 this season.
PSG is still the strongest team in France, no doubt about it. However, teams like Marseille, Monaco, Lens can push them. They managed to beat Lens last week. However, they had never won before that. If Marseille is lucky this year, it is of course possible for them to become champions. PSG is still not fully compatible.
