Even though Sevilla have not won a single match from the two group stage matches, I am sure that Arsenal will never easily beat them at the Ramon Sanchez-Pizjuan Stadium. I do remember how strong Sevilla were last season in Europe until they knocked out Manchester United, so Arsenal need to be wary of losing instead of being confident of winning.
I think Sevilla can get points in their home game against Arsenal regardless of whether it is 1 point or 3 points. If the match ends in a draw, then of course that's fair, but if Arsenal loses then I think that's really bad for Arsenal. Favorites to win are Arsenal, but Sevilla should not be underestimated at home.
If you look at Arsenal current performance in the English Premier League, they are unbeaten, most recently the Gunners beat Man City, who we know are the defending champions in the two most competitive competitions in the world, EPL and UCL. Meanwhile, Sevilla experienced different conditions in La Liga, they only won twice and lost 4 times, the rest were draws. Currently, in my opinion, the victory over Man City will be a valuable asset for Arsenal when facing Sevilla. I predict Arsenal will be able to secure full points at home to Sevilla.
Even though Arteta squad has suffered one defeat, the fact is that they still have a one point difference with Sevilla, who were only able to draw in the previous two matches. On the other hand, there are still four matches left in the group phase, I think Arsenal still has a great chance of winning group B and qualifying for the round of 16.
