Manuel Pellegrini insists Manchester City still have work to do after their Champions League last-16 first-leg win over Dynamo Kiev. City produced one of their best performances of the season to put one foot in the quarter-finals with a 3-1 victory in Ukraine on Wednesday night.
First-half goals from Sergio Aguero and David Silva put City in control before Yaya Toure made the result safe late on, after Vitaliy Buyalskiy scored during a Dynamo fightback.
