ROBERT (via email) wanted to know if DJ's long-range header against Northern Ireland was the best headed goal of his career?
It was actually against Wales, Robert. Archie Gemmill delivered a tremendous cross and I put my head on it from the penalty spot and it went screaming into the net.
It was probably the best headed goal of my career.
