VIDEO: Sergio Aguero gives City win at Old Trafford

Back in April 2013, Man City travelled to Old Trafford to face Ferguson's Man Utd side. The Red Devils were 15 points clear at the top and needed just 10 points to win the league.

After a goalless first half, James Milner put the Sky Blues ahead  The home side were back level when Vincent Kompany turned the ball into his own net. Then, 12 minutes from the end, Sergio Aguero gave City victory. Yaya Toure had the ball inside United's half and he found Aguero, who dribbled into the D and round a few defenders before firing past De Gea in the United goal.  Take a look at the Argentine's goal above!
