It's just that PSG needs hard work to beat Arsenal who are playing at home.
When comparing PSG's squad to Arsenal's squad, Arsenal's squad has to be put ahead. But PSG's squad has plenty of talented players. Players are talented if they have less experience. And PSG have been able to perform very well this season with the help of Luis Enrique. So even though Arsenal team is strong, PSG has a chance to perform well and get points in this match. We got to see a good performance from PSG in Ligue 1. Despite not winning by a big margin in the Champions League match, PSG managed to secure 3 points in the first match. So hopefully we will see a better performance from PSG against Arsenal as well. Luis Enrique will definitely want to get full points.
Looking at the betting exchange, Arsenal is more favored than Paris Saint-Germain. but I'm quite doubtful, because Arsenal was previously held to a draw by Atalanta. or maybe because this match was played at the Emirates Stadium, Arsenal's home base. in addition, Arsenal was able to hold their arch-rivals Manchester City to a draw in the Domestic League. for me Paris Saint-Germain is not an easy team to beat. even though, this match was held at Arsenal's home ground. but in fact of course I want Arsenal to win their match when hosting PSG, so they get points to improve their ranking in the group stage. well, if Luis Enrique wants full points in the meeting of these two teams. especially Arsenal, who are playing in front of their own supporters, The Gunners. I can't speculate at this time, especially since I haven't received information regarding the line-up and system that will be implemented by Arteta. anyway, Arsenal has a chance to beat Paris Saint-Germain in the battle between the two teams in this group stage.
