Defoe, who went to South Africa in 2010 but missed out in 2014 in Brazil, is back in the England fold and determined to stay there for the tournament in Russia.
A summer move to the Cherries was to ensure he was playing in the top flight after Sunderland’s relegation, and he is hoping he can impress for his club to ensure he gets the nod for his country.
He told Sky: "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.
"It's the pinnacle and to get the opportunity again would be really special, especially with this group of players.
"I believe this group has got so much more to offer and so, of course, that's the dream, the dream has not changed since day one to play in a major tournament."
