Of course, most people would not have expected that Brest would play that well, and most people simply thought that PSG would really dominate because they were playing in front of their own supporters.
PSG has also their bad moments regardless of how good Brest they are. Besides, Brest are interestingly holding the third place in the ranking before all of Monaco, Lille, Lens and Marseille. That reminds me of Girona in La Liga.
With that draw, PSG remained first but the points difference between them and Nice decreased to 6 points which is still reassuring for them.
By the way, 6 matches out of 9 ended up with a draw in this round, including mainly the top 7 teams apart from Nice.
