Arsenal is so strong in the Premier League this season, They are unbeaten in the domestic league, but in the Champions League, Arsenal lost to a team that was not seeded. Lens was able to beat Arsenal with a score of 2-1 in the previous match which made arsenal record in the Champions League slightly tarnished. But I think arsenal will win again when they face Sevilla in the next match.
This is quite true however I am hopeful that Arsenal will bounce back against Sevilla. Odegaard is a fantastic attacking midfielder who could assist Saka to score starling goals in the match but it is unfortunate that Saka may not be able to play in the next match. I hope he would have fully recovered by then.
In terms of experience, it is possible that Arsenal players do not have enough experience in the Champions League because you can see that arsenal players are dominated by young players and they have just returned to the Champions League after being absent in the previous season. I think Arteta must be able to raise the enthusiasm of his players in the upcoming match against Sevilla because arsenal must try well in order to qualify for the next round.
The need for the club to qualify will give them that moral booster to win over Sevilla. So far so good, Arteta is a well experienced manager being an assistant manager to Pep Guardiola for the range of 3 to 4 years and his calmness and aptitude will give him that edge to win the next match ahead.
