Arsenal could actually be more favorites because they are the hosts in this match. And I personally will also have higher hopes for Arsenal for the first leg. A draw could indeed happen. but I still think Arsenal's chances of winning are much greater for the first leg. I also expect both teams to score goals in this match. And I hope there are more than 2 goals for today's match.
Mikel Arteta really has to be able to take Arsenal to the UCL final because it has been a long time since this team made it to the UCL final. And it looks like Arsenal is only reaching the UCL final for the first time. namely in the 2005/06 season. And since then Arsenal have not managed to return to the UCL final. And Arteta must make new history for Arsenal in the UCL. And that will be a source of pride for Arsenal fans. And Arteta's name will certainly be remembered by many Arsenal fans in history.
I can't perceive Arsenal as a favorite in this match, although they went well in the group stage, much better than PSG, but PSG are favorites for me even in this away match for them. The match will definitely be difficult, but I think that PSG can win today. You shouldn't think that Arsenal is already in the final just because they were able to beat Real. If Arteta can reach the final, it will be unexpected, if they can win the Champions League at all, then he will be forgiven for all the seasons when Arsenal was second in the Premier League, but there are Barcelona and PSG, it seems to me that these teams are stronger than Arsenal.
