At first I also predicted that this match would end with a very narrow score, even a draw was a very possible result. In the first half Arsenal was able to lead by 1 goal and they managed to maintain it until the first half ended. In the second half, Manchester City managed to equalize, at that time I thought the rest of the time would be a tight match. However, not long after Arsenal was able to take the lead again, even Manchester City equalized and after that Arsenal was able to create 3 other goals which finally made them win with a very convincing score. Manchester City's defense in the second half was really problematic.
Before start of game things were completely on balance or narrowly favorable for Arsenal because they were host club while in first half Manchester City done good job despite conceding goal but in second half suddenly Arsenal charge started, and they hammered Citizens badly which ended worst for them.
A big win for Gunner which will give them good confidence and also their moral could be high even though chances are not high for them to challenge Liverpool for title race but with this result now they can feel good for having another time second spot which was not looking good few weeks back. Manchester City problems in defense are wide open with their attack is also not working as it needed or working few before this poor run challenges are going to increase if they fail to keep their momentum and increase their quality which is important right now.
