Sunderland have completed the signing of Toronto striker Jermain Defoe for an undisclosed fee.
Defoe, who left Tottenham Hotspur for the MLS at the start of 2014, has penned a three-and-a-half-year deal with the Black Cats in a transfer that also sees Jozy Altidore move in the opposite direction.
The 32-year-old told the club's official website: "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."
Defoe is available to make his debut against Spurs at White Hart Lane on Saturday afternoon.
