Manchester City's undefeated run of 28 games across the competition has been broken by its city-rival, Manchester United.
United defeated CIty 2-nil, in a game that was held in City's home at the City of Manchester Stadium.
ManU took an early lead via a penalty after CIty's Jesus brought down Martial inside the box with a clumsy challenge. Bruno Fernandez converted the penalty in the second minute of the play.
Luke Shaw scored the second goal for Manchester in the 50th minute.
With the win, United has now registered three consecutive wins against City. This first such time since the run of four-win between November 1993 and November 2000.
Despite the loss, Man-C is reigning at the top with 65 points from 28 games.
Manchester United at the second is far behind with 53 points from the same number of games.
