Manchester City manager Pep Guardiola says his side "have to be more clinical" despite seeing another dominant display sweep aside Borussia Monchengladbach for a 19th successive win.
Guardiola's team - favorites to win their first Champions League title this season - were far too good for their meek last-16 opposition in Budapest, and perhaps should have added to the first-leg lead given to them by Bernardo Silva and Gabriel Jesus.
"In general, we controlled the game. Unfortunately we were not clinical enough up front," Guardiola told BT Sport.
"That is something we have to improve in this competition. Up front we have to be more clinical. In this competition you have to be perfect to make sure you go through."
Silva headed in a wonderful cross from Joao Cancelo to open the scoring, before the same two players combined to lay on the second for Jesus.
Gladbach, appearing at this stage of the competition for the first time in 43 years, had no answer and would need something close to a sporting miracle to turn the tie around when the sides meet in Manchester on 16 March.
