It's hard to believe if that Sevilla was able to beat Arsenal in the Champions League match because Sevilla performance in La Liga was less than optimal and different from Arsenal, who performed amazingly in the Premier League and managed to second.
Even though Arsenal experienced defeat against Lens, I think Mikel Arteta will learn from this mistake and try to improve the club condition to be able to perform optimally in the Champions League match.
After Arsenal managed to beat Manchester City in the Premier League, I am more confident that Arsenal will be able to get points from Sevilla in the next match, and I can confirm that Arsenal will be able to qualify for the next round in the Champions League.
The next match is an opportunity for both teams to be the best and get full points in order to be in a better position in the group standings. But there is also truth in what you say, where Mikel Arteta will continue to provide better encouragement to his team so that they can win at Sevilla's home ground later. Because Arsenal also has greater self-confidence after being able to beat the best team in the Premier League in recent times, Arsenal will try to perform as hard as possible to achieve victory in the next match in the Champions League.
