Owen, McManaman and Garcia immediately spring to mind. Zenden, Litmanen, Anelka, Morientes Possibly Reina?
In fairness getting them all quickly was good work between you. Got told it by a scouser on the train from Birmingham up to Liverpool for the Manc game. He said it was asked in a quiz in Liverpool recently and most of the teams were well short of the 12.
