Because since there able to win the champion league this season; they want dominate the entire next coming season, and in my view arsenal can make that happen with how they improve their performance better, But nevertheless let us be wait and see what can actually happen in UEFA Champions league we can't make an early predict.
That is just how every team prepares against upcoming season, all teams are getting ready for the fresh season adding more quality to their team to ensure they perform better than last season. Champions League have always been tough right from the very start so next season will definitely be an interesting and challenging season i don’t expect less from the league of champions.
The likes of Arsenal, Bayern Munich, Leverkusen are all teams we should watch out for because they cannot be underrated this time around. Arsenal seems to be improving every season and Bayern Munich and Leverkusen both have promising coaches now so they are bound to perform better because all eyes will be on them.
