Every team will put their best players on the field. That's why I think they will play with a rotation squad in the matches they play in their own league. This situation will be less challenging for Paris Saint-Germain than Liverpool because the French league is not a very challenging league like the Premier League. That's why Paris Saint-Germain will be able to rotate as they wish.
How many rotations can they make to put them in a position to be the better team to win? I doubt they can make anything good out of the rotation of squad they are going to do. The champions league is the league of champions and at the same time you’ve to be a worthy team even in your league to stand a chance to play here. The problem here is that PSG don’t usually face big opponents that will give them a very hard time for the league title every season and that is why they’re the champions of the league year in year out. Their strength in the champions league cannot be matched with what they showcase in the Ligue 1. For them to qualify from this stage, they need to be better in quality performance than what we see them showing now.
