Man Utd v Man City : Sir Alex Ferguson: Felt Manchester United were unlucky against Manchester City

Manchester City reduced Manchester United's lead at the top of the Premier League to 12 points.

Vincent Kompany and James Milner both hailed a 'massive' win over Manchester United, with the Manchester City skipper hoping the result will build momentum for next season.

Sergio Aguero's fine individual effort on 78 minutes earned City a 2-1 victory at Old Trafford which cut United's lead at the top of the table to 12 points with seven games left to play.

Though the Red Devils are still overwhelming favourites to wrap up a 20th title, Kompany wants City to finish this season positively to take momentum into the next campaign.

"Every game, we have to play to win," Kompany told Sky Sports 1. "I do believe that the way we finish this season is going to have an impact on next season.

"You're always going to start from the beginning and it's a good game to have under our belt to take into next season."

Milner, who opened the scoring early in the second half, also wants City to build momentum, with Roberto Mancini's side facing Chelsea in the FA Cup semi-final at Wembley on Sunday.

Milner: We deserved the win

The midfielder added: "Regardless of where you are in the table, the derby is a derby and to beat your rivals is massively important. We came here, we worked hard and got the win.

"We've got good momentum going into the weekend."

Kompany was unfortunate to concede an own goal which drew United level and the City captain feels the reigning champions deserved to take the points.
