Pep Guardiola had miscalculated by not starting either Rodri or Fernandinho and it was the Spaniard, the match-winner in Istanbul, who remained on the bench when an attempt to change things was made far too late.
City made a similar start to their second Champions League final against Inter, when nerves of the occasions clearly put them off their usual game.
