"Lower division sides like Bournemouth are an important part of English football," Defoe told the Sunday Mirror. "I loved my time there. The people and the fans were brilliant to me. I've got great memories of my time at Bournemouth.
"I hope everything works out for the best."
Defoe, who joined the Cherries on loan in September 2000, hit 10 goals in 10 games while on the south coast to equal John Aldridge's post-war record of goals in consecutive matches.
He added: "Bournemouth provided me with many of my early experiences of competitive football and there's a lot of Premier League players who started out by doing something similar.
"I progressed a lot while I was there. I scored goals and it meant everything fell into place for me when I returned to West Ham."
