It was a painful result for Revel. PSG scored exactly nine goals and there were just as many missed opportunities. He struggled from the start of the PSG match until the final whistle. It wouldn't have happened if Mbappe didn't score a hattrick in this match and he did it, I had no doubt about him, we are now used to him scoring hattricks in such matches.
PSG does not show mercy against such easy opponents, for some reason they always achieve such different results.
In this match, PSG showed no mercy to their opponents every time there was a chance to score, it would be a goal. It seems like PSG wants to give a signal to their opponents, especially in the UCL League, that they are ready to face them at any time and of course a big win like this increases the players' confidence even though the opponent is a weak team like Revel. However, it must also be acknowledged that a small and weak club like Revel is still trying to withstand PSG's attacks, they are not giving up even though they lost by an absurd score.
Apart from that, it is also clear that PSG really needs Kylian Mbappe at PSG and they don't want to lose Mbappe. because Mbappe always launches real attacks in the opponent's penalty box with his speed, so it's not surprising that in that match he scored a hat trick. Any team playing for mbappe will benefit from his mentality and pace.
