Sunderland have completed the signing of England striker Jermain Defoe from Toronto FC with Jozy Altidore heading in the opposite direction.
The Black Cats have confirmed that the 32-year-old former Tottenham frontman has signed a three-and-a-half-year deal after completing a swap with United States international Altidore.
Defoe said: "I am delighted to be here and I'm looking forward to the challenge. It is a great club and I've always enjoyed coming up here and playing against Sunderland because of the stadium and the supporters. It is a great place to play and I'm really looking forward to it."
