So far PSG have won all three of their games and in an impressive fashion as well so it will be difficult for Brest to get something out of this. Of their last three games, it's only one win they have to boast of and sitting in 12th place doesn't help their case either. I see this game going a bit one way and that is in the favor of PSG because Luis Enrique's men will be looking to continue in their sterling ways, adapting well to life without Mbappe and I do not see Brestois being a problem, or maybe they can if they play their cards right since in football anything can happen.
After the international break, I expect some of the Paris Saint Germaine players who went to represent their national teams to feel some kind of fatigue because of the stress of flying to different countries but for Brest, most of their players didn't get invitations from their respective national teams. PSG game against Brest this weekend will be played at the Parc des Princes in Paris which is a home of the French champions so despite the inconvenience in the PSG camp, I still expect them to easily get all three points from the game
