The performance of PSG is not as bad as a lot of people portray it to be, they are top of the table, winning 10 out of 14 games and have only drawn 4 which for me is a good run for the French champions and it seems to me that they might still retain their title since no other side seems to be putting any pressure on them. The only issue PSG are having this season is their poor run in the champions league where they've had to struggle much this season and seem not to be able to make it to the next round.
Yes, what happens is that Ligue 1 is known to be heavily dominated by them, that's a fact, but the games where they really have to make the difference are in the UCL, that's Where the value of each team is seen a lot, but there's no need to be surprised, good teams like Madrid are not Very good in the UCL, and they are getting ahead, so they have to be very consistent, Luis Enrique has to Pull his A up his sleeve because he can't expect much , the fact is that now everyone wants and expects a lot from PSG and some are disappointed.
