Giles grew up in
Ormond Square, a
working class area of inner-city
Dublin, where he developed many of the skills that would aid him in becoming a professional footballer. He was encouraged to enter the game through his father
Christy who played for
Bohemians in the 1920s and managed
Drumcondra during the 1940s. Growing up, Giles remarked "I didn't consider myself Irish". This was due to the outsider status of association footballers in the mainstream sports-life of the Republic, where Gaelic Games were a much more dominant force in the '50s of his youth. Giles was spotted in Dublin playing for
Stella Maris, before he began his English career with
Manchester United. He joined
Matt Busby's team for a £10 signing-on fee in 1956. He was given an early first-team debut in 1959 after eight of the team died in the
Munich air disaster in February of the previous year. Among the dead was
Bill Whelan, who was five years older than Giles and also came from the Cabra district of Dublin. He was also chosen to play for the
Republic of Ireland team by the age of 18. Giles was a regular first-team player over the next four years, playing alongside
Bobby Charlton and
Denis Law. Manchester United won the
FA Cup in
1963, where Giles played the defence-splitting pass which started the move towards a winning goal by
David Herd. After being out of favour, he asked for a transfer and joined
Leeds United for £33,000. "I am going to haunt him", is what Giles said of Busby, to his wife Anne, after the Scotsman had forced his departure when freezing him out of the starting team. Giles would soon evolve into one of the finest central midfielders in England, as Leeds won the
Second Division title in his first season there. In 1965, he was in the team which came close to a
League championship and
FA Cup "
double" but missed out on both, to Manchester United and to
Liverpool respectively. Giles formed a strong partnership with
Billy Bremner as Leeds manager
Don Revie built a new team around them. The players had similarities in their styles and were a tremendous foil for one another. Giles was known as the creative force and Bremner as the ball-winner, but each was capable of doing the other's primary job. In the
1967–68 season Leeds won both the
League Cup and the
Fairs Cup. That was the first season in which Giles was affected by injury, which meant he missed the second leg of the Fairs Cup final. In the
1968–69 season, Giles was instrumental in Leeds becoming league champions in a then record 67 points from 42 matches at 2 points for a win, a record that stood for ten seasons. In
1970, Giles again had a magnificent season as Leeds chased three trophies but lost all three, the League went to
Everton; the
FA Cup to
Chelsea after a
replay; and the
European Cup campaign ended at the hands of
Celtic in the semi-finals. In the fifth round of the
1971 FA Cup, when Leeds were unexpectedly beaten 3–2 by
Colchester United, Giles scored Leeds' second goal as they almost came back from 3–0 down. Leeds regained the
Fairs Cup but lost the League title on the last day, with
Arsenal getting the victory they needed to earn the championship and form one half of a successful "double" bid. Leeds won their first
FA Cup and Giles his second when they defeated Arsenal 1–0 at Wembley in
1972, yet again they missed out on the League on the final day of the season after defeat to
Wolverhampton Wanderers.
Sunderland and
A.C. Milan beat Leeds in the finals of the
FA Cup and the
European Cup Winners Cup in 1973, rendering Leeds trophyless again.
Jack Charlton's retirement in 1973 also left Giles as the most senior member of the squad. In the same year, he started to combine his Leeds duties with a spell as player-manager of his country. In 1974, a 29-match unbeaten run at the start of the season helped Leeds coast to their second title, but then controversy reigned after Revie quit to take over the
England team. Revie recommended to the Leeds
board of directors that Giles, nearly 34 and approaching the end of his playing career, should be his successor. The board instead appointed
Brian Clough, a brilliant manager but a controversial choice as he had been publicly critical of Leeds in the past and was not an admirer of Revie. Clough and the players never got on – the players had wanted Giles too – and the board reacted by dismissing Clough with a big pay-off after just 44 days in charge. Giles still did not get the job though (that went to
Jimmy Armfield) and concentrated on playing as Leeds chased a place in their first European Cup final. Giles himself never applied for the Leeds vacancy on those two occasions, his name had instead been put forward as a candidate by others. Also in 1974, Giles was nominated—along with
Danny Blanchflower—by
Bill Nicholson as his successor at
Tottenham Hotspur. The Spurs board appointed
Terry Neill instead. Giles was outstanding in Leeds' European campaign but was no longer an automatic fixture in the side. After appearing in the
1975 final, which Leeds lost 2–0 to
Bayern Munich, Giles accepted an offer in June 1975 from
West Bromwich Albion to become their player-manager, while still playing for and managing the Irish team. ==Status within the game==
