Will go down in Pittodrie folklore as the man who scored the Dons most important goal in their 100+ year history on that rainy night in Gothenburg. A feat that helped him, rather unfairly, earn the title of 'super sub'. John was another local lad who joined the Dons in 1979 from Middlefield Wasps and impressed enough to earn his debut against St. Mirren in December of that year. The following season he established himself in to the Aberdeen first team along with youngsters Cooper, Simpson and Black in what was the first clutch of 'Fergie Fledglings.'
Although he will be remembered for important goals against Bayern Munich and Real Madrid as well as several telling strikes in the Scottish Cup, Hewitt's performances in the 1985-86 campaign were a vital part of that particular double season triumph. He made 364 appearances for the Dons scoring 89 goals in the process. Significantly 12 of these goals came in the European arena placing him as the Dons second highest European scorer. To add to his European medals Hewitt collected a clutch of domestic winners' medals in his career including appearances in the Aberdeen side that won the Scottish Cup in 1982 and 1983 as well as supplying two goals that helped defeat Hearts in the 1986 Final. He completed his full set of domestic medals in 1985 when Aberdeen won the League Cup and John also picked up the man of the match award.
Hewitt was somewhat reluctantly transferred to Celtic in 1989 and also had a brief spell in management with Dundalk in Ireland. This spell included a winning goal for the club against Aberdeen in the summer of 1996. John eventually returned to his native Aberdeen where he still works to this day.
