The 35-year-old joined the Cherries on a free transfer over the summer after spending two years as Sunderland’s leading man.
Defoe forced his way back into the England fold earlier this year, however, he has been overlooked by Gareth Southgate during the most recent World Cup qualifiers.
The former Tottenham man is hoping his form with Bournemouth this season will be enough to convince Southgate that he can be an asset in Russia next summer.
Defoe told Sky Sports: "In a World Cup year, you always want to do well for your club because it is based on merit.
“To get into a squad, you have got to be playing well for your club, it's as simple as that. As a forward, you have got to be scoring goals to get into the squad.”
Bournemouth have struggled to pick up positive results this season and currently sit 19th with Defoe having only hit the back of the net once in seven appearances.
The south coast club travel to face Tottenham on Saturday and punters using their free bet may want to back Defoe to get on the scoresheet at Wembley.
