I know Arsenal is not the only team that has beaten City this season, but Why should anyone dictate how you celebrate when your team fights hard for a win?
Arsenal scored a goal, and they celebrated. They win a game, and they celebrate. Isn’t that what football is all about?
Arsenal may or may not win the League, but they destroyed City, and we must give Arsenal due respect for beating City ruthlessly and with pure class.
If it was the other way round, they would have mock Arteta again and say all kind of things and you know why they do get away with, it's because Arsenal has a way the fan base forget quickly and focus on the next thing, this is what they would have thought but you don't disrespect people and expect sympathy later, it doesn't work like that way.
In the first leg they played, if not for some of Arsenal players errors, they would have even won that first match but they couldn't but they juts prove they are above Manchester City in all ways, even if they couldn't win the league, they have given their fans the joy needed.
