Manchester City powered into the Champions League quarter-finals on Tuesday as Sergio Aguero's double paved the way for a 7-0 rout of hapless Schalke in the last 16-second leg. City had snatched two late goals to win the first leg 3-2 and they made the most of that fightback with a ruthless demolition job at the Etihad Stadium to clinch a 10-2 aggregate victory.
