Brest couldn't make a good start to this season indeed. But I'm not surprised. Their performance in the previous season was such an extra that it is difficult to expect the same thing. They don't have such squad to be competitive every season. This kind of teams sometimes have a really good form throughout a season. Like Girona example in the La Liga. The only difference might be that Girona had a better squad.

Coming back to the game, PSG should be winning this one without big problems. PSG are also not the same. They are even stronger since parting ways with Mbappe, lol.
It's surprising to see that Brest has lost two games and won just one in three games. They are playing in the Champions League because they finished third last season. Brest fans would have been expecting a more fruitful season. This poor performance might be an indication that they will not do well in Europe. The club didn't do well in the transfer window. Maybe it was because of a lack of funds. They signed some average players such as Mama Balde, Kamory Doumba, and Julian Le Cardinal; others were loan players. Anyway, we cannot conclude a team with just three games, they might improve as they play more games.
Last season was a glorious journey for the Brest, even since the beginning of the season they have been able to continue to stick tightly to PSG in the ligue 1 table although at the end of the season they started to experience inconsistency and must to end the season in the third positions, Brest have actually tried to improve the quality of their squad in the summer transfer market but so far we not seen any improvement in their squad, Although it is too early for us to judge them, but it seems that this season Brest will not be able to repeat all their achievements like last season, with a tight schedule and also a squad that can be said to be not too luxurious, of course it is difficult for them to compete, especially the Champions League, I think Brest will be one of the teams that will come out of the Champions League quickly and for this season most likely they will only be a team that is in the middle of Ligue 1, because many other teams who has improved the quality of their squad better than Brest.
