He most recently served as head coach of Major League Soccer club Minnesota United until October 2023.

As a manager, Heath initially worked in his native England before moving abroad to Orlando City, an expansion side in the American second division.

Orlando City had the best start of any newly founded team in the history of American soccer,[4][5] winning multiple honours before joining MLS in 2015.

Known as "Inchy" due to his small stature, he burst on to the first team scene in 1979–80 displaying great maturity in the First Division and scoring two vital goals at the end of the season which ensured Stoke's survival.

[2] With Heath fast becoming one of the most sought after midfielders in the country Richie Barker allowed him to join Everton, who were being managed by Kendall, in January 1982 for a then club record fee of £750,000.

Grabbing a poor Kevin Brock back-pass, Heath scored a goal away at Oxford to equalize the match and earn Everton a chance to turn things around.

[7] Heath was a key member of the successful Everton side of the mid-1980s, winning two league titles in 1985 and 1987 and the FA Cup in 1984.

[15][16] Heath was appointed manager of USL-1 expansion team Austin Aztex in February 2008[17] after a meeting with owner Phil Rawlins in a pub in Newcastle Under Lyme.

After their successes in the USL, Orlando City was granted an expansion franchise in MLS for the 2015 season with Heath at the helm.

[19] In November 2016, Heath was hired as head coach for Minnesota United prior to their first season in MLS after a tenure in the North American Soccer League.
