Manchester City delivered a ruthless attacking display to rout Manchester United 4-1 in the Premier League on Sunday, the first derby between the rivals since the retirement of United manager Alex Ferguson.
Sergio Aguero volleyed home an acrobatic goal in the 16th minute, Yaya Toure doubled the lead in the 45th minute and Aguero scored his second goal in the 47th. Samir Nasri's 50th-minute goal completed the burst at the start of the second half.

''It's horrible to lose the derby - it's always horrible. It's worse when you lose in this way,'' United captain Nemanja Vidic said.
While City gained a big win under new manager Manuel Pellegrini, who replaced Roberto Mancini after last season, United has struggled since Ferguson left after nearly 27 years. United (2-2-1) is eighth with seven points under new manager David Moyes, its poorest Premier League start since 2004-05 season.
''I've made them aware of what I think,'' said Moyes, whose team earned just one point from matches against Liverpool, Chelsea and City.
