Arsenal is like this every season and their dominance always breaks when they approach the end of the season. Stumbling at the end has become a tradition for the Gunner. So if you believe Arsenal can win their first trophy from Man City, maybe you need to look at Man City with a bad game. But can this happen if currently Man City still promises to be the only club that is difficult to beat?
Lack winning mentality make Arsenal have loss opportunity for winning domestic league, last season become most longer team on top standings position but can't consistency actually on several last matches have loss first standings placed and Manchester City success take Arsenal position become the winner. I think Arsenal have stop with bad tradition lack winning mentality on second half season, they have consistency until become the winner and never loss consistency actually with crucial matches. Left many matches in Premier League and Arsenal still in the same ration chance for winning Premier League with Manchester City, but Arsenal need to improve their performance when facing crucial match and never loss points from crucial matches against Man City, Liverpool or another top standings teams.
