Manchester City have announced the death of their former captain Tony Book at the age of 90.
In a tribute, the Premier League club hailed Book as one of the all-time greats, having captained the club during a golden era of success.
“It is with great sadness and with the heaviest of hearts that we announce the passing of former Manchester City captain and manager Tony Book, aged 90,” read a statement from Manchester City.
“A true club legend in every sense of the word, Tony played 315 games for City in total between 1966 and 1974, scoring five goals.”
The right-back joined Man City from Plymouth Argyle in 1966 and was named club captain the following season.
Book, known as 'Skip', led Manchester City to the First Division title in 1968.
He also lifted the 1969 FA Cup, before leading the club to the League Cup and the European Cup Winners' Cup in 1970.
Book was named joint winner of the Footballer of the Year award in 1969, an award he shared with Dave Mackay (the only time the award was given to two players).
He became manager of Manchester City after his retirement in 1974, a position he held until 1979.
During his reign as manager, Book led Manchester City to the 1976 League Cup and a second-place finish in the First Division in 1977, losing the title to Liverpool by one point.
Book would later serve as a youth coach at the club, leading Man City to their first FA Youth Cup success in 1986.
He was appointed honorary president of Man City and became life president of the official supporters club.
Man City stated that Book remained “a very popular member of the matchday legends at our Etihad home games”.
Club president Khaldoon Al Mubarak paid tribute to Book following his death.
“For almost sixty years, Tony helped shape Manchester City,” he said. 'Not only in what he contributed as a player, captain and coach, but in the way he behaved.
Book served as honorary president of Man City and life president of the Supporter's Club.
'His hopes and ambitions for his club were only matched by his incredible humility regarding his own significant achievements.
“Our fans will always remember him as a man who helped lay the foundations on which unprecedented success could be built.
“A player and leader whose extraordinary skills not only helped us return to the top of English football but also earned us our first European honour.
'Tony's devotion to his club meant he was still fulfilling his duties at the club earlier this season. “I will greatly miss seeing him at our games and witnessing first-hand the respect that each generation of the City family has for him.”
