Indeed for several seasons now Arsenal has not been able to win the premier League, so just like you said there efforts and determination last season was very impressive but there hard luck on wining the premier League still follows them even if they have managed to top the league again, so I think I will agree with those that said Arsenal will not be able to win the premier League this season even if they are currently on the top position because one thing about Arsenal in terms like this when you feel they have stabilize there performance then they will surprise you in the next minutes by losing form so for now we cannot conclude there stand.
Arsenal looks like this season will extend its failure to lift the EPL trophy, even though it is currently in first place, but is very vulnerable to dropping again. In the remaining 10 matches, Arsenal is more difficult than their two rivals Man City and Liverpool. Of these 10 matches, Arsenal will still face Man City, MU, Tottenham, Chelsea and Aston Villa, all of which have the potential to lose points for Arsenal.
To be able to force victory on a team like this, you need a strong mentality and you must try to pursue goals quickly so as not to reduce the winning mentality to being a loser. If they fail to score goals in crucial minutes, it will be a heavy burden for Arsenal players. Indeed, in football anything can happen, but looking at Arsenal's remaining matches, it seems difficult for Arsenal to win the EPL league trophy.
Yes, if you look at the remaining schedule, the road for Arsenal is very tough, the hope of winning a trophy this season seems difficult to realize unless they are able to perform strongly in every match until the season is over. The Gunners' strength will be tested in their next meeting against Manchester City, this match is a "semi-determining" match to make things easier if they are able to beat City. In a situation like that, it is very clear that mentality is a strong bet, Arteta must be able to provide an injection of morale for his young troops so that they don't slip up like last season.
