Both teams are on a mission to win this match, especially since Arsenal was only able to draw 0-0 on the first Matchday against Atalanta. On the other hand, PSG won 1-0 over Girona through an own goal from Paulo Gazzaniga, although they achieved different results, but they were both unable to score in the opening match. Arsenal will try to show their strength at the Emirates stadium even though their opponents are unbeaten in Ligue 1, this victory is very important for them to improve their position in the standings.
Obviously, Arsenal will be the favorite team because of the factor of playing in front of their supporters and their strength has also been tested when facing strong teams in the EPL.
The meeting between Arsenal and PSG in the Champions League in the upcoming match could be a fairly fierce match because both teams will try to win even though I personally also favor Arsenal as the team that will be able to win in the match. But Arsenal must play better and not make more mistakes that result in more cards, because PSG must also be considered a very dangerous team this season, especially if this is a match in the Champions League where generally all teams will bring out their best abilities.
In my opinion, if Arsenal can't control it well, then they will play under pressure because they have to get 3 points that they haven't gotten in the first match, and maybe their advantage is that they will play as hosts, but it can also be a disaster for them if they feel burdened by their status as hosts.
On the other hand, Paris Saint Germain is in a fairly good condition because they bring the capital of victory from the first match even though their victory was not apart from the luck they got in that match. But still, it will be a good capital for them in the second match of the Champions League. I think they will target at least 1 point for them to bring home from this match.
