Half-back Mackay made his name at Hearts in Scotland where he landed the Scottsh League, Scottish Cup and League Cup, success that led to a first Scotland cap in 1957.
He was voted Scottish Player of the Year in 1958 and won another League Cup before his £30,000 move to Spurs in March 1959.
Famed for his tough tackling, stamina, enthusiasm and never-say-die attitude, Mackay was a magnificent all-round player with superb skills, passing and an eye for goal.
He was a regular throughout the double season and glory, glory days of the early 1960s where he dovetailed perfectly with half-back partner Danny Blanchflower.
A stomach problem kept him out of out 1963 UEFA Cup Winners Cup triumph and injury would dominated for the next couple of seasons - many feared his career over when he broke his leg against Manchester United in December 1963 and having missed the rest of the season suffered the same bad break again just three games into his comeback.
But he was back in August 1965 and, having taken over as skipper, he proudly held aloft the FA Cup at Wembley after our triumph in 1967.
After 10 years at the Lane he was granted a transfer to Derby County who he helped to the Second Division title and was named joint Football Writers' Player of the Year.
Management was a natural step for Mackay and after spells at Swindon and Nottingham Forest he took Derby County to the First Division title in 1974-75.
He also managed at Walsall before a nine-year stint in Dubai and later with Doncaster and Birmingham City.
Described by Bill Nicholson as his best signing, Dave Mackay was the heartbeat of the double-winning side and one of the club's greatest players.
