Nelson passed eight 'O' Levels and 3 'A' Levels (French, Geography and Geology) and had the chance to attend Loughborough University but accepted the offer of a professional contract at Southend instead.[5] Nelson also wrote two memoirs about his professional career, Left Foot Forward and Left Foot in the Grave. The books are written in diary form, chronicling a season with Charlton (1994–95) and Torquay (1996–97) respectively. The books have been generally well received, and noted as showing the real life of "ordinary" professional footballers, became best-sellers, and each was shortlisted for the William Hill Sports Book of the Year award.[6][7]
Career after retirement
After retiring from the game in 1997, Nelson became commercial executive of the Professional Footballers' Association. In 2018, he was still playing football, regularly turning out for Chapel United in the Southend Borough Combination Veterans League and Charlton Athletic veterans.[8]
