The current PSG squad has more experience than the Arsenal squad and if we’re going to rate this match on experience by each team, we may give the winning in the end to PSG which in my opinion it can’t be that easy for them to attain. PSG is a very strong team also, their dominance in the champions league in the past cannot be forgotten, they’re also up to the task to prevail in this match too.
Experience in what form mate?
There are some set of new players in the squad who have fewer Champions League experience, and we know how PSG's performance is in the Champions League; and also, considering Arsenal's defensive quality, I don't think PSG will easily win Arsenal in this game.
We can't talk about the experience as of now, PSG are currently having it on top of their league which automatically puts them on the level of being a competitive team to face in the Champions league but not forgetting that the League in which PSG plays cannot be strictly compared to the Premier league, since the EPL seems a lot more competitive i think we will be giving out the option directly for Arsenal to win or at worst a draw in my opinion.
Arsenal defense is already a hard wall to crack, not even PSG are qualified enough to break in easily, Manchester City tried and we all know how it ended if not for the red card then the result of that match must have ended in favor of Arsenal with a victory.
In many aspects, for now, Arsenal deserve to be the favorites.
I think it's not just about their ability to put up a tough fight against a team like Manchester City, but it must be admitted that Arsenal have indeed developed into a better team under Arteta. The only similarity between the two is that they don't have a sharp striker, but collectively, all the players in the squads of both teams have the ability to score goals with various variations.
However the match ends, both of them still have a long journey (6 matches remaining) to reach the last 16. Of course, both teams are ambitious to beat each other, Arsenal clearly has a slight advantage because they are playing in front of their own supporters.
In terms of experience, although both teams have never won a trophy, Arsenal and PSG have good bargaining power in the Champions League. That's what makes this match interesting, besides both are dominant teams in their respective domestic competitions.
