Manchester City Manager Pep Guardiola insists there are still many ways that his team can improve.
City have been in irresistible form in recent weeks, thrashing Liverpool, Watford and Crystal Palace in their last three English Premier League games.
They scored 16 goals in those matches without conceding.
City will play Shakhtar Donetsk at 6.45am Wednesday in the UEFA Champions League.
