Defoe completed his move to Bournemouth on a free transfer earlier this afternoon, having been allowed to leave the Black Cats following their relegation from the Premier League last season.
The 34-year-old scored 37 goals in 93 appearances during his two-and-a-half-year stay at the Stadium of Light, and he expressed his desire to see the club back in the top flight as soon as possible.
