Many feared Mackay's 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 come back he did and he proudly held aloft the FA Cup at Wembley after our triumph in 1967. That made it three FA Cups and one title but injury forced him out of the 1963 European Cup Winners Cup triumph.
After 10 years at the Lane he was granted a transfer to Derby County, who he later steered to the championship in 1974-75. He also managed at Swindon, Walsall, Forest and Birmingham.
Appearances/goals: 268/42 (Lg), 33/4 (FAC), 17/5 (Eur).
