It won't be too difficult for Arsenal to secure a victory against Sevilla, even though they're playing away from home. Arsenal's fate is still in their own hands.
Well Arsenal are in a better condition to win the game based on their performances in the this season however they lost their last UCL game against Lens therefore I don't think they'll be ready to concede another defeat against Sevilla, judging from both teams performance currently it's very obvious that Sevilla are the weaker side even though they'll be playing with a home advantage, they're currently 14th in the Laliga standings why Arsenal are 2nd place in the EPL and recently won the champions league holders Manchester City.
Well Sevilla is not a team to be underestimated cause they're not very good at attacking but they've can be very good defensively on a good dsy and their defense can cause alot of problems for Arsenal's front 3, Arteta should just hope another player from their front 3 doesn't sustain an injury in that match.
In the same opinion, Arsenal will visit Sevilla headquarters with high self-confidence, Arteta squad has forgotten its defeat against Lens and is enjoying an even bigger victory after beating Man City in the EPL. We know that Sevilla did not start their campaign very well this season in La Liga, while in the UCL they had the same fate as Milan in Group F who achieved a draw in the two matches they have played. With these facts, there is nothing wrong if Arsenal is superior, even though Sevilla acts as host.
The Gunners still have one slot as the favorite team to qualify from the group phase even though they are runners-up, while PSV and Sevilla can't do much in Group B it seems. I think even though Sevilla's defense is getting better, it's not a problem for Arsenal who are in top form in getting full points.
I genuinely have no doubt that Arsenal is going to win this match against Sevilla. Arsenal is in a far better form compared to their opponent. But there is one thing, you know Arsenal will have to face Chelsea just before the match. Probably only three days before they face Sevilla. So that might be a problem.
But I still do not think that it is going to be a major issue. Sevilla is performing really badly anyway. So Arsenal should not have too much problems being able to beat them. I am expecting a win from Arsenal, and if it is anything other than that, even a draw, it is going to be really surprising in my opinion at least.
