Mario Balotelli has no doubts the Manchester derby will soon eclipse Barcelona v Real Madrid as the biggest game on the planet.

Balotelli's Manchester City go to Manchester United on Sunday.

He insists it will not be long before it even eclipses the 'El Clasico' showdown between Spanish giants Real Madrid and Barcelona.

The controversial Italian striker, 21, said: "Maybe now, City v United is a better football match than Milan v Inter.

"If I was sat at home and could watch one of the two, I think I'd watch United v City.

"Barca v Real Madrid is the biggest for the history - but soon United v City will be the biggest derby in the world."
