Arsenal are focused on the Premier League, I'm sure they don't think much (if not at all) about the Europa League. As for Barcelona, even if it is a favorite, the bookmakers quotes are simply ridiculous:
UEFA Europa League 2022/23 - FC Barcelona reach Round of 16?
Yes - 1.57
No - 2.25
Being able to beat underdogs with a great percentage of efficiency is certainly good, but in big games Barcelona are weak this season.
Barcelona goes to the europa league caused by it's not as good as the team who qualified for last 16 in UCL. that proves that barcelona is always having horrible results when it comes to battling against big teams. I just remind you of the match against intermilan. I remember how many people favor barcelona rather than intermilan but inter was kicking barcelona's ass to go down to the europa league.
MU is coming with new squads under ten hag. This gonna be the toughest match for barcelona in europa league. I don't see any other team that is at the same level as MU except arsenal.
Barcelona has horribel result last season in europa league after being beaten by frankfurt.
I remember very well the confrontation between Barcelona and Inter, as the bookmakers considered Barcelona to be the undisputed favorite. I immediately said that this is nonsense and I made my bets on Inter in the Champions League pool. Unfortunately the second game ended in a draw (although Inter should have won both times) but overall I am very satisfied because in the first game I guessed the correct score.
