Sunderland striker Jermain Defoe has re-signed for former club Bournemouth on a free transfer.

The England international, 34, who has signed a three-year deal, said: "It's great to be back. The one thing I can guarantee is goals."

"It was an easy decision, joining a top team with a top manager," added Defoe who scored 15 league goals last season.

Cherries boss Eddie Howe said Defoe's signing is a "huge moment for the club".

Defoe is Bournemouth's second signing of the summer, following the arrival of goalkeeper Asmir Begovic from Chelsea.

"We want to bring players here who can have a big impact on our continued rise and we believe Jermain fits that as a natural, proven goalscorer," added Howe.
