Sergio Aguero starred as Manchester City beat Monaco 5-3 in a breathless and dizzyingly end-to-end Champions League last 16 first-leg encounter at a rocking Etihad Stadium on Tuesday. Raheem Sterling put City ahead, only for Kylian Mbappe to level and Radamel Falcao to score twice -- the second goal a magnificent chip -- as Leonardo Jardim's side moved into a 3-2 lead. But City struck three times in the last 19 minutes, through Aguero's second goal, John Stones and Leroy Sane, to put Pep Guardiola's men in charge ahead of the return leg on March 15. For a long time it looked likely to be a scarring night for City, who reached the semi-finals last season, as a succession of calamitous defensive errors allowed Monaco to take control.
