Who could head the ball furthest, hardest or most accurately?
Next up in our Big Question series, we're looking for your views on who was the best-ever header of the ball at United.Whether it was a defender making vital clearances or a forward with an eye for a nodded goal, it takes a certain type of courage to foolishly put your head in the way of boots, fists and other heads.
Which players have United had that fit into that category? Was it a defensive lynchpin, such as Colin Clarke, Gary Briggs or Mark Creighton, or was it a goal machine along the lines of Billy Hamilton, Paul Moody or Tommy Mooney. Or someone else entirely?
Join the debate on Twitter; give us your views - using the hashtag #OUFCBigQ - and we will publish the best responses in Saturday's match programme for the Barnet game.
