From their performance when it comes to UCL, I think PSG has gone far more than Arsenal. It is juat that PSG hasn't been able to win UCL. Arsenal performance is not too good when it comes to UCL and that was why they were unable to win their last match but PSG struggled till the end and finally got a dying minute goal.
Back to domestic leagues, PSG is doing better than Arsenal in their different leagues and PSG remains the number one, though, they have no rival. Arsenal doesn't have that zeal and passion to stay focus and achieve their goal at the end of thw season which has being a big problem to them. PSG might win the match based on my own analysis.
Even so, it is not certain that PSG will be able to win their match when visiting the Emirates Stadium. although Arsenal only produced a draw against Atalanta, at that time Arteta had not found a formula to handle his team because their team captain Odegarard was absent from Ciceda. on the other hand, PSG at that time had difficulty breaking through the Gorona goal. in fact, the goal was created due to a mistake by the Girona goalkeeper. referring to these two teams in their Domestic League, of course the competition is different, we know that. Arteta has a goal to bring Arsenal to win the Domestic League trophy, unfortunately some of their players are injured. referring to the betting exchange, the odds for both teams have quite a difference. in this match, Arsenal is more favored. it can be said, because they are playing at home, the Emirates Stadium. IMO, this match will present a fairly fierce battle. a duel of tactics and strategies from both coaches will occur, but if Arsenal is in prime condition, they have a greater chance than PSG in the battle between these two teams.
