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.
I think the reason why he believes so is because PSG has been on the champions League almost every season, so that means that they are use to things about the champions League unlike the Arsenal that doesn't use to be consistent on the champions League, so if the experience he really meant is about the champions League he is actually correct but however it doesn't mean that Arsenal is a vulnerable club for them to win.
So if you ask me I cannot say that PSG is better than Arsenal because Arsenal use to be very fierce on there matches especially this season, though the only thing about Arsenal is that champions league use to be a very difficult for them because it was only through struggle they got to the point they did last season.
