Micah Richards has signed a new contract tying him to Manchester City until 2013.

The 19-year-old is one of the hottest properties in the Premier League and had been linked with a £20 million move to Chelsea.

Having started his City career on the right side of defence, he has excelled this season as a centre-back alongside Richard Dunne.

The news comes as a major boost for the club, who travel across Manchester to face neighbours United in the derby on Sunday.

Manager Sven-Goran Eriksson said: "This is fantastic news, it shows we are building for the future by securing one of our most talented players on the longest term contract."

Fair play for staying at city. So many players have gone to chelsea i.e Sidwell and parker and have been bench warmers. Atleast at city he will play week in week out.
