The intrigue in the French Ligue 1 is already dead, the Parisians are leading in the standings with a gap of 12 points. So now PSG will be more fixated on cup and European Cup matches.
Rennais unsuccessfully spends the current season, in Ligue 1 the team goes on the 8th place, falling behind the European Cup zone on 3 points. In the cup the team had only 1 serious opponent - Marseille, which Rennais defeated at the stage of 1/16 finals at home.
PSG is now in great shape, I have little faith that Rennes will be able to win in Paris.
Prediction: PSG to win. We recommend the “1 Win” bet, odds 1.45
