Manchester City boss Sven Goran Eriksson says Micah Richards is the best young defender he's worked with after the 19 year-old's masterclass yesterday against Manchester United.

At no stage did the 19-year-old look flustered and at no point did Carlos Tevez, Ryan Giggs or Nani threaten to get the better of him on a personal basis.

"It is important to remember this young man is 19," said Eriksson.

"I don't remember having a defender that strong and that quick at any age. That is a combination that is very rare indeed.

"He wins everything in the air and can fight with any centre-forward and then, if he makes a mistake, he has the speed to repair it.

"His pace is incredible. At 19, you just don't see that."
