It will not be easy for arsenal to hold a draw or even win Manchester city with their current form and performance in their previous game. I think there are things to put into consideration on Arsenal title race. We have to understand that the match will be played at Etihad stadium, the Man city home on 26th April, they will play Chelsea and Newcastle on 29th April and 7th May respectively. All this matches should be considered big games for the gunners, which I think Arsenal can not come out of them victoriously. That's where I'm drawing conclusions that they won't be successful in winning the premier League because they won't be able to win their remaining matches .
Arsenal performance isn't bad, but Arsenal is high likely will not win against Manchester City because if you check on their head to head, Manchester City always win regardless the league and where the match were played. So I assuming Manchester City already get extra 3 point, Arsenal must win in their next matches otherwise Manchester City will overtake them.
It's really sweet achievement if Manchester will win FA Cup, Premier League and Champions League in this season.
