However, other Ligue 1 teams also have good quality and strategy to stop PSG. We can find one fact that PSG always seems to have difficulty winning Ligue 1 matches because other teams employ total defensive strategies throughout the game, that's obvious why you shouldn't underestimate them.
In the last two matches PSG still failed to win the match when they were held to a draw by Lorient and Toulouse, but we really know that PSG was able to dominate the game well. The point is that even though most Ligue 1 teams don't have expensive players like PSG, in fact they also have a lot of quality players. It's just that their market value is not higher than some Premier League players in the bottom or mid-table teams.
I don't think anything can break PSG's dominance as a candidate for the trophy in Ligue 1 this season. PSG can make a comeback to achieve victory in the upcoming matches. The two matches they have played is not a bad measure of their performance as psg are still the strongest team in ligue 1 for this season. Indeed, in the last two matches PSG could not win because their strength was not balanced enough in these two matches.
Even this season we have seen their performances statistically in the last two matches where they were able to dominate the game quite well. In week three of Ligue 1 this season PSG will face Lens and I think this is psg come back game to winning ways.
