I believe Arsenal can go further in the Champions League and also try as hard as possible in the Premier League, the most important thing is that Mikel Arteta can always overcome existing mistakes without having to feel pressured because Manchester City will always remain their main competitor. I have seen in the last 2 seasons actually Manchester City is not much different from Arsenal, as long as this club remains focused, then they can break Man City's dominance.
Arsenal have high team-spirit in past season and they've everything to win but there's certainly one excluded quality they need to add and that's the mentality of becoming Champions. Mere watching their games especially their league matches, one would easily noticed their incredible tremendous performance against mediocre clubs but when it comes to elite ones, they're a little bit shiver but at the end of the day, they get the work done. My point exactly is for Mikel Arteta to improvise strategically solid method for winning major titles and maintaining balance in his team's streak winnings.
