Although PSG only won two trophies last season in Ligue 1, they are still quite satisfied with their treble-winning campaign after winning the Champions League, their first time. This season, PSG will continue to strive for every trophy available in Ligue 1, although I have some doubts about their ability to repeat their success in the Champions League, as the competition there is fiercer than in any other domestic league. As for Marseille, they clearly haven't developed enough to surpass PSG, even this season, even though the season is still long. However, Ligue 1 is always easier to predict from the start because there is only one very strong team: PSG.
The Ligue 1 trophy already is not looking like a challenge to them but the champions league may pose to them a huge challenge such that they may crash out even before getting close to the finals. I am not wishing them the least but football can be really funny and it is once said that it is more difficult to defend a trophy than winning it. Like I will always say, for this season they should rather focus their energy on winning the league 1and other titles and accept any fate that befalls them in the champions league.
