Now 37-years-old, former England Under-20 international Wallwork started his career at Old Trafford, making 19 league appearances in nine years with the club.
Young Player of the Year in Manchester in 1996, Wallwork won a Premier League winners medal in 2001, and was an unused substitute for United in their 1999 Intercontinental Cup victory over Palmeiras.
Having left Old Trafford in 2002, a move to West Bromwich Albion beckoned, and he spent a fairly successful six years at the Hawthorns, although he failed to add to his trophy tally. His career at West Brom was interjected by a number of loans away from the club, with Bradford, Barnsley and Huddersfield all catering his talents across a number of years.
He signed for Sheffield Wednesday in January 2008, although he lasted until just May before the club released him, and he has since gone six years without a career as a footballer. A number of issues in his private life have restricted opportunities since, with jail sentences and an injury sustained in a stabbing incident stalling his career.
However, it has been confirmed by the official Evo-Stik League website that Wallwork has come out of imposed retirement to sign for Ashton United.
Ashton currently sit in 18th place in the Evo-Stik Premier Division, having picked up 12 points from 11 games. Wallwork will be looking to improve the fortunes of the non-league club, with his experience of the top flight invaluable, despite his long time out of the professional game.
