Regardless of Sevilla's current form in both the league and in the UEFA Champions League, playing against them in an European game at the Ramon Sanchez-Pizjuan Stadium is one of the scariest matches for any European club because Sevilla are always playing at their best whenever they're playing an European game in front of their home fans.
Arsenal I think knows truly well of the kind of task they're trying to execute and I think Mikel Arteta's men are ready for the encounter. On papers, Arsenal are the favourites to win that game but they must be at their best to take all three points from that game
So basically it is quite difficult for Arsenal to get the full three points against Sevilla. I'm pretty sure that this match has a tense intensity. Sevilla can overwhelm Arsenal even with ideal players. Personally, I would not underestimate Sevilla if they were playing at home. This is a tough task for Arteta and his troops to better control their emotions and be calm. As usual, the mentality of Arsenal players will always be tested and in the Champions League competition it will not be the same as what they experienced in the Premier League.
When it comes to the europa league I'm very sure of Sevilla because their performance in the europa league used to be extraordinary, they put their best performance in every game they play no matter the team, but as for champions league I'm not too sure about Sevilla if they can succeed to defeat arsenal. Arsenal are doing well this season, and I don't think the champions league is a game that they will take for granted, looking at the players arsenal have compare to that to Sevilla it very possible for arsenal to defeat Sevilla.
Let's look realistically at the performance of these two teams since the start of the season, it is clear that there is a significant difference in fact, Sevilla has never found its best performance and Arsenal is very on fire now so I think if there are no surprises that happen then it is very possible for Arsenal to beat Seville easily.
Regardless of the team's performance in the domestic league or UCL, I think the team's performance in its last few matches is clear and we can look at this to predict it.
