This is Millwall.
Millwall is an English soccer team that has fluctuated between the second and third tiers of English soccer for most of its existence. They spend a couple of seasons in the top division in the late 1980s, they made it to the semi-finals of the FA Cup a handful of times, and once they even made it to the FA Cup Final - they lost, but qualified for European play for the only time in their history.
I was in London in May of 2010, when they played Swindon Town, the winner to be promoted from the third to the second league of English football.
