David (Dave) Mackay  (14 November 1934-2 March 2015) began his playing career with the club he supported as a boy, Heart of Midlothian. “Just to get near Tynecastle was a dream,” he said. “I was a Hearts fan all my life; I used to walk the three miles to Tynecastle, go early to get under the turnstile because I couldn’t afford to get in. So when Hearts came along to sign me, I couldn’t believe it.He won all three Scottish Domestic honours with the club before signing for Tottenham Hotspur for £32,000 in March 1959. George Best branded him his toughest and bravest opponent. Jimmy Greaves, called Mackay  “the most complete professional footballer I have ever known”. During the 1960s his fierce determination and skill contributed to the team which won the Double in 1961, further FA Cup victories in 1962 and 1967, and the Cup Winners Cup in 1963. In 1968 he was transferred to Derby County for £5,000, after Brian Clough persuaded him to sign. In his first season at the Baseball Ground, the club gained promotion to the First Division and  he was chosen FWA Footballer of the Year jointly with Manchester City's Tony Book.  In 1971 he was appointed player-manager of Swindon Town but left after just one season to take charge of Nottingham Forest. He remained at the City Ground until October 1973, when he returned to Derby as manager following Clough's resignation. In his first season Derby finished third in the table.  In his second season in charge of Derby, he guided the team to the 1975 league title. The following season, he managed the club to a respectable fourth-place finish in the league, the semifinals of the FA Cup, and an unfortunate extra time second-round exit to Real Madrid in the 1976 European Cup. Mackay was sacked in November 1976 following  a poor start to the season.  After an uneventful year-long spell as Walsall manager from March 1977 to August 1978 he spent nine years coaching in Kuwait. He returned to the UK and was appointed manager of Doncaster Rovers in 1987. Mackay's reign at Belle Vue lasted two seasons before he moved to Birmingham City, who had just been relegated to the third tier of the league for the first time in their history. He failed to get them promoted to the Second Division and resigned in 1991. He then returned to the Middle East for two years managing Zamalek, a Cairo club team, and then a further three years in Qatar before retiring from football altogether in 1997.
