Manchester City added to Sunderland’s misery after smashing them 4-1.

Raheem Sterling opened the scoring by heading in Kevin De Bruyne’s cross.

The lead was doubled through Yaya Toure’s low 20-yard drive before Wilfried Bony headed in another de Bruyne delivery.

The brilliant Belgian calmly scored before Fabio Borini’s consolation, as Bony skied a penalty later on.

Sunderland did little to trouble a rampant City side and remain in the bottom three.
