Obviously, you hope that a player will respond to a move to a higher league or a bigger club. But playing outside the top flight - or even outside the Football League - doesn't necessarily condemn you as a bad player. Several Bournemouth players were playing for them in the lower leagues. And some players can continue well into their thirties.
From Wikipedia; [Tony] Book followed Malcolm Allison again [from Plymouth Argyle] to
Manchester City two years later, this time for a transfer fee of £17,000. Manager
Joe Mercer was initially reluctant to spend such a fee on a player over 30 years old, but was persuaded after Allison pointed out that Mercer's career had included a successful move at a similar age, when he joined
Arsenal from
Everton aged 32.
Book prospered under the management of Mercer and Allison. He made his Manchester City debut in the opening match of the
1966–67 season, a 1–1 draw with
Southampton, and became a near-permanent fixture in the team. In his first season at the club he missed just one game, becoming the inaugural winner of the club's
Player of the Year award in a season in which the club consolidated their position following promotion.
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.
