With the way PSG struggled to win against Nantes and Angers, I was surprised that PSG scored 6 goals against Toulouse because I never expected them to score that amount of goal against Toulouse that have won their two matches this season. Toulouse was able to score more two goals against PSG because PSG were so relaxed after they have scored 6 goals against Toulouse.
PSG have a lot of potential and I think they don't want to play at full strength every game in Ligue 1, but sometimes the players come out on the pitch in a good mood and they play well, on those days they will score a lot. I think everyone knows what PSG are capable of in their best games, so we can expect so many goals from them sometimes. Their motivation in Ligue 1 is not so high because they have no doubt that they will be able to defend their title again, and they will pay more attention to the Champions League.
