Career
After joining Tranmere from Motherwell in 1979, Mungall went on to make more than 500 Football League appearances for Rovers in a 17-year period. This spell saw Rovers rise up the league and make several appearances at Wembley. He remained with the club on the coaching staff before leaving in October 2000 to pursue business interests.
But he was quickly back in football and was given his big management opportunity in October 2001 at Chester.
The Blues were struggling in the Football Conference when Mungall took over, initially as caretaker-manager. But a dreadful run of form saw Chester dragged into serious relegation trouble and Mungall was sacked after a defeat to Northwich Victoria on 26 December 2001.
Mungall was later on the coaching staff at Droylsden, a role he left in December 2007. On 13 February 2008, Mungall returned to Chester City as assistant manager to Bobby Williamson but he left along with Williamson early the following month.
