Has to be Mark Bowen for me, I was only a kid but he was right up there with our best players during arguably our best ever period and he was one of those players who had the ability to play anywhere (in fact according to wiki, he played left midfield in his first season here). He'd of been a decent striker, he knew how to find the back of the net.
Adam Drury spent most of his career in the Championship, "best left back outside of the Premier League" he may well have been (words of Barry Fry), but Mark Bowen was surely one of the best left backs in the country?
329 of his 410 league games came in the top division of English football, 8 consecutive years in the top division with Norwich. 5th, 4th and 3rd place league finishes. Oh yeah, and the scorer of the second goal against Bayern Munich away....
