In Group B, there will be an interesting game between Arsenal and Sevilla, Sevilla fired their coach because of the bad performance they had in La Liga in the past and they surely want to get better results in the Champions League too but Arsenal is the team they won the game against Manchester City and in this season, Arsenal had an amazing performance so far which enough to say they won't have a hard game against Sevilla. The last time they faced each other was the Europe League in which Sevilla won the game and now this is a good chance for Arsenal to take revenge.
Even though Arsenal has a stronger chance of beating Sevilla in the Champions League, this match is extremely difficult to predict. Despite Sevilla's recent terrible performance, which led to the sacking of their coach, I don't think Arsenal will have an easy time winning them. They are the Europa League favourites, but now that they are in the Champions League, they will want to do everything they can to enhance their play in order to advance to the next round (knockout stage) of the competition. Arsenal will come for nothing less than a win, which means they will have to put in more effort in order to defeat Sevilla. Sevilla might still be regaining their form for now first since after sacking their coach but that is not enough condition to feel that Arsenal can win them easily in this match.
I think that horribler performance from sevilla is still become a night mare for the club even though the next game will be happening at home for sevilla but im doubtful if sevilla will able to take full points from arsenal. I hope sevilla will be winning the game but seeing the result from emirates cup last year made me feel doubt if sevilla will able to win against arsenal easily at home. Hosting the game will be boosting the morality from the players but it will not be so significant as the result will also depend on the quality of players too.
Sevilla needs to work even harder in scoring against arsenal since the gunners have very good squad this time. Everything is still remain possible for sevilla to beat arsenal.
The club needs to work harder in the defensive line caused by it has become the main weakness of sevillla. We are still far away from the continuation of UCL.
I hope that will give enough time for sevilla to prepare everything.
