Problem:Passage: In the 1967 close season, Book was named captain following the transfer of previous captain Johnny Crossan to Middlesbrough, and was henceforth nicknamed Skip by his teammates. His first season as captain was a very successful one, leading Manchester City to their second league championship and playing every game. An Achilles injury sidelined Book for the first four months of the 1968–69 season, but he returned to the team in time for the start of their FA Cup run. In the week preceding the cup final, Book was named the 1969 Football Writers' Association Footballer of the Year Award, sharing the accolade with Dave Mackay. The following Saturday Manchester City played Leicester in the FA Cup final. Manchester City won 1–0, and captain Book lifted the trophy. The following season City became the first English team to win a European and domestic trophy in the same season, the European Cup Winners' Cup and the League Cup. Book retired from playing in 1974, passing the captaincy to Colin Bell. He made 242 football league appearances for the club, and for many years was City's most successful captain in terms of trophies won.
