Brought to Arsenal as a decent left-back, Emmanuel Petit’s strong defensive displays and good range of passing saw him tried out in central midfield for the Gunners, where he formed one of the great all-time partnerships with Patrick Vieira.
10) Vincent Kompany
Initially a midfielder when he joined Manchester City, Vincent Kompany did not particularly impress in that role in his early days with the club, though he excelled as a defender, becoming one of the best centre-backs in the world for a few years.
