After his retirement from playing he joined the coaching staff at
Aldershot, before assisting
Ian McDonald. After Aldershot went out of business in 1992, a new club,
Aldershot Town was formed, and Wignall became their first ever manager, winning back to back promotions before former club
Colchester United signed him in January 1995. During his time at Colchester he led the club to promotion via the
play-offs in 1997/98 and to the
final of the
Associate Members' Cup the year before. He stayed as manager until he resigned in January 1999, believing he had taken the club as far as he could. In April 2000, he joined
Stevenage Borough and was offered a two-year contract but never signed it and, when approached a month later by former club
Doncaster Rovers, he decided to manage them instead, having only managed 8 games at Stevenage. In 2009, Wignall published his autobiography titled
You Can Have Chips. ==Honours==
