Thia actually a really good one that PSG won away from home and for Monaco it's a pretty poor one loosing at home by such margin even if we know that PSG is much bigger and ahead of them both in depth, form and even position on the table, although Monaco isn't a weak team but weren't just a match for PSG , the dominance of PSG has continued and its gradually becoming that they are going to undoubtedly be the winners of the league title thia season.
It is very difficult to beat Paris Saint Germain, even though the opponent has the status of a club that can be counted on with good performances and also playing at home. In fact, I also think that one of the things that can make Paris Saint Germain lose is that they are unlucky, or the opponent (whoever it is) has very great luck. No one can deny that Paris Saint Germain is the best club in Ligue 1, but unfortunately only in the domestic league can they compete and dominate. While when they are in a bigger competition they can't do much, like their progress in the Champions League which always fails every season.
