I am still fairly confident that PSG will dominate Ligue 1 again in the new season. Even though they don't seem to be making many new player transfers at the moment. I read that Stade Rennais has spent the most money in Ligue 1 during the 2025 summer transfer window. They have already spent around €26 million to sign Jeremy Doku from Anderlecht, even surpassing PSG. It seems that Stade Rennais' spending is an effort to qualify for the Champions League, and they are not hesitating to invest aggressively to pursue high achievements in France and Europe. Last season they finished in 12th place. I can't predict, but maybe they can pull off a surprise.
Fully no doubt for PSG winning Ligue 1 next season, looks how much money spent out to sign new player and season by season very easy to be the champion. Looks the Ligue 1 table every season PSG become the winner with many points remaining from 2nd standings team and winning around several Ligue 1 matches remaining. PSG have completed player right now and not really needed to sign new player during not any player leaving the team, Dembele, Donarumma, Achraf Hakimi, Marquinhos, Willian Pacho, Khvicha Kvaratskhelia and many top player still not leaving PSG for next season.
In my prediction, around games week 28 to 30 will win Ligue 1 such as did every season how early games week for PSG become the winner of Ligue 1.
The ligue one is always for PSG to lose because in terms of investment PSG is way ahead of the rest of the other teams PSG is the team that will continue to win the title until other teams wake up from their sleep because with what I have seen in the French ligue 1 the plan of other teams is just qualifying for Europe and for the bottom teams escaping relegation
