Arriving from Motherwell for £100,000, in 1979, after scoring 80 goals in 166 appearances, Pettigrew was known as one of the most clinical finishers in Scotland. It is during his time at Motherwell where he would be called up by the national team, earing five caps, where he would be competing for a place against the likes of Kenny Dalgleish, Joe Jordan and Derek Johnstone.
During his time in Dundee, Willie would lift the Scottish League Cup back to back in his first and second years at the club where United would almost win the cup double in the 80-81 season getting so far as the final before Rangers would beat them 4-1 at Hampden in the replay as the original fixture ended 0-0 after extra time. Davie Dodds would score the only goal for Dundee United during the game.
After the final Dundee United would cash in on Pettigrew, making a profit after selling him to Hearts for £120,000. It is here where Pettigrew would help Hearts gain promotion to the top flight.
This kit resembles the Netherlands 76′ that is also on the website. As both are made by Adidas and use very similar colours although Adidas moved with the times and over the next five years they would introduce their own branding on the front of the shirt and on each of the numbers used on the back. The collar has also changed from a round neck to a more modern ‘V’ neck with a large collar being black to contrast the bright tangerine colour of the top.
