Kevin De Bruyne and Riyad Mahrez both scored twice as Manchester City restored their lead at the top of the Premier League to six points with a 4-1 derby victory over Manchester United at the Etihad Stadium on Sunday.
United had put up a decent fight in the first half, going in 2-1 down at the break, but City's quality showed after the interval with Ralf Rangnick's side looking increasingly demoralised.
