The Big Question: Who Was United's Best Defender?

Continuing our series, we wonder who the best Oxford defender was

While it's generally the goalscorers who grab the headlines, every successful side needs those players at the back whose job, primarily, is to stop the opposition from scoring. Over the years, United have had some excellent exponents of the defensive arts, both in the full-back and centre-back positions.

What we would like to know, though, is who was United's best? Which defender stands head and shoulders above the others? Who was the most effective at keeping out opponents' strikers? Let us know on Twitter @OUFCOfficial using the hashtag #OUFCBigQ and the best responses will be published in the Good Friday programme for the Stevenage game.
