Play polo at Arsenal Emirates Stadium?

So an emirate is an airplane? The Arsenal Airplanes? Yea, Emirates sounds better at least!
Surely a team in Arsenal should have a name relating to weaponry or something? Like the wiki suggests...

Football

In 1886 workers at the Arsenal formed a football club initially known as Dial Square after the workshops in the heart of the complex, playing their first game on 11 December (a 6-0 victory over Eastern Wanderers) in the Isle of Dogs. Renamed Royal Arsenal two weeks later (and also known as the 'Woolwich Reds'), the club entered the professional football league as Woolwich Arsenal in 1893. Today it is known simply as Arsenal F.C., having moved to north London in 1913. Royal Ordnance Factories F.C. were another successful team set up by the Royal Arsenal but only lasted till 1896
