Andy Gray a débuté sa carrière de joueur professionnel à Dundee United où il marqua 46 buts en 62 matchs de championnat écossais. En octobre 1975, âgé de 19 ans, il file à Aston Villa fraîchement promu en première division. Menant le front de l’attaque Gray va remporter lors de l’exercice 1976/77, le trophée de meilleur buteur du championnat avec 25 réalisations. La saison suivante ses 29 buts lui permettent de remporter le trophée du meilleur jeune joueur du championnat ainsi que celui de meilleur joueur du championnat élu par ses pairs (un doublé historique qui sera réitéré seulement par Cristiano RONALDO 30 ans plus tard). A cette époque Andy GRAY fût le plu jeune joueur de l’histoire du championnat anglais à recevoir cette distinction.
Andy GRAY started his professional career as a player with Dundee United where he scored 46 goals in 62 appearances. In October 1975, at the age of 19, he headed south to Aston Villa (newly promoted to the First Division) and won England's golden boot in 1976/77 with his tally of 25 league goals. His 29 goals in the following season earned him the PFA Young Player of the Year and PFA Players' Player of the Year awards (a historic double not repeated until Cristiano Ronaldo won both awards 30 years later). At the time he was the youngest player to earn the Players' Player of the Year award.
Andy GRAY then moved to Villa's local rivals Wolverhampton Wanderers in September 1979 for a then-British record £1.5m. After scoring the winning goal for Wolves in the 1980 League Cup final, he remained with the club through their relegation in 1982 (despite interest from Manchester United) and promotion a year later. He moved to Everton in November 1983 for £250,000. He enjoyed two seasons with the Merseyside club, winning the FA Cup in May 1984 (scoring in the final against Watford). A year later, he won the League Championship and European Cup Winners' Cup, also scoring in the final of the latter. He also reached another FA Cup final, but this time he was on the losing side as Everton were defeated by Manchester United.
Then came the arrival of England striker Gary Lineker from Leicester City in the 1985 close season. Despite angry petitions from Everton fans wanting to keep Gray at Goodison Park, he left the club on 10 July 1985, returning to Aston Villa in a £150,000 deal. Despite starting the decade on a high as league champions in 1981 and European Cup winners in 1982, they had now declined to mid table mediocrity and the return of Gray was unable to turn things around as his arrival at Everton had done. He scored five goals from 35 league games in 1985–86 as Villa narrowly avoided relegation to the Second Division, and the following season he failed to score a single goal from 19 league games as Villa fell into the Second Division. He began the 1987–88 season still with Villa, but was transferred to their local rivals West Bromwich Albion in September 1987 having not featured in a first team game for Villa that season. His spell at Albion lasted less than a year, and was uneventful as they narrowly avoided relegation from the Second Division. In mid-1988, he joined Rangers. He spent one season at Ibrox, helping them win the Scottish Premier Division title – the first of nine successive titles they would win. He dropped into non-league football with Football Conference club Cheltenham Town before retiring in 1990.
Gray's Player of the Year accolades in England were not enough to convince Scotland manager Ally MacLeod to select him for the 1978 World Cup squad, as he was somewhat controversially excluded. Gray won 20 caps for Scotland, scoring 7 goals for his country. His full international debut came on 17 December 1975 in a 1–1 draw with Romania. His final senior appearance for Scotland came on 28 May 1985 in a 1-0 win over Iceland in a 1986 World Cup qualifier. This had been his first cap for two years, despite him scoring twice in his penultimate appearance for the national side on 19 June 1983 in a 2-0 friendly win over Canada, and him excelling on the club level for Everton after his transfer to the Merseyside club later in 1983. He was not selected for any of Scotland's World Cup squads during his playing days but he was into the two Panini album sitckers of 1978 and 1982.
