There are 9 matches left and PSG is very comfortable at number 1. The difference of 19 points, they are very comfortable. I think they are also ready to make a record by going unbeaten this season. It seems that the League Title can be known sooner, even if PSG loses 6 times PSG is still the champion of Liga 1. It seems that this effect makes PSG very comfortable in the UCL. They were able to get rid of Liverpool as the favorite.
But I think for the UCL champion is still very difficult, there are big teams waiting. But for the semifinals, I believe the favorite PSG will qualify for the semifinals, because they will meet Aston Villa. Regarding Dembela, you are right that the statistics are extraordinary, it seems that in Barcelona he had a lot of injuries but at PSG he was the main player.
Based on my observations, PSG will regain the League One trophy because from their quality and the standard of others, they are the best team for now. The nineteen points difference will be difficult for any club in the French League to overturn. I am also hopeful that PSG will do well in this season's UCL league. We saw them beat the competition favourites. Not that they were lucky to win, but they were the better team in both legs. Aston Villa is an underdog that is doing well in the competition and has one of the most tactically sound and experienced coaches, Unai Emery. But in terms of quality players, PSG is a better side and Luis Enrique is not also doing badly as a manager m
It is like a settled deal that PSG will win the league one with no team to challenge them. The team that is second to them is Olympique Marseille which PSG won confidently in their last match. Assuming PSG becomes engrossed in the champions league and decide to focus all their energy and resources there, they will still win the league title even if they draw the rest of the French Lig matches. I strongly feel that their focus now is on the champions league and not their league matches.
