Manchester City have worked their way through a fair few managers during their long and often tumultuous history but many who have succeeded in the hottest of hot seats fall into a similar category.
Among the many studious types to reign at City was Manuel Pellegrini, the taciturn Chilean who one could hardly imagine getting animated at his own wedding. Pep Guardiola's predecessor sometimes transmitted a cool confidence and on other occasions a grim detachment, depending whether his glassy stare was accompanying a 6-0 win or a 3-0 defeat.
Part of the criticism leveled at Pellegrini was that he lacked a rapport with the crowd, a mirror image of the problem that befell Mel Machin in the late 1980s.
