Manchester City boss Sven Goran Eriksson says he's never worked with a defender as talented as Micah Richards.

The Swede reckons Richards has been a key part of his side's superb start this season which sees them lying third in the Premier League.

And Eriksson said: "He has been excellent for England and Manchester City - whether at full-back or centre- back, he's been excellent.

"He is so strong but quick as well. I have never seen a defender like him who can make a mistake but still be quick enough to recover."
