London - Sunderland completed the signing of defender Anton Ferdinand from West Ham Wednesday.
The defender, who joined for a fee believed to be around 8 million pounds (14.7 million dollars), has agreed to a four-year deal.
"We needed to strengthen our defence and Anton is a great signing," said Sunderland manager Roy Keane.
"He's still young but he has over 160 games under his belt so he has experience, he's learning his trade. He'll bring quality and competition for places, which is what we want.
"Hopefully we can take him to another level here at Sunderland - he has come through the ranks at West Ham and maybe just needs a change."
Ferdinand is Sunderland's ninth signing of the season. (dpa)
