We always heard how PSG is good because of money, picking top players...etc but what happens all the time is that the other teams are just failing and missing points vs weaker teams. Brest 1-1 Marseille was the newest thing but Lille, Rennes, Lens weren't any better..
PSG will play vs Monaco and Lille next. If it wins against them, I suppose by the 11th round (vs Marseille), the difference will be 10 points (again).
Yes exactly that's the point, they are dominating the league 1 not just because they are strong but because there is no real competitors that can make troubles for them and play for the title, always other good teams loos points with weak teams
