It is difficult to predict at the start of this season, some people even say the same thing when club competition in League 1 becomes more difficult or more competitive and for PSG to compete at home to Lyon and this is something that haunts PSG, the fear of failure like last season when they still had Mbappe and Messi competed against Lyon at home. PSG couldn't win the match and this is the concern that has arisen again and the best advice in this match is not to bet because something can happen even though Mbappe looks strong with the quality of his talent but Lyon has beaten PSG at home and this match is at home to Lyon and I predict either a draw or a loss.
But my hope is that at least Mbappe as a mainstay player is able to score a lot to win but if not it is better to use a defensive formation for a draw than to lose embarrassingly.
I don't think with Ligue 1 is difficult for predicting who will be the winner, actually PSG is favorable team for winning Ligue 1 in this season although with not well start last several matches before. Current stop standings managed by Monaco and Marseille is not existing for longer time and PSG will return to the top standings position. PSG is the only one teams in Ligue 1 have busy activities in transfer window than other Ligue 1 teams haven't much money for signing new player.
Still Mbappe in player list make easily for PSG keep as favorable teams for winning Ligue 1 tittle in this season, no doubt PSG is most favorable teams become the winner and if bad happening first half season they will sign many new player again how to defend their Ligue 1 tittle last season.
