The former Tottenham striker kicked off his MLS career in fine fashion by scoring three goals in his first two outings but has missed TFC's last three matches because of a hamstring injury.
As Defoe prepares to return for Toronto's clash with New England Revolution this weekend, the 31-year old forward quietly has his sights set on a possible call-up to the England squad for this summer's World Cup.
"It's been really frustrating because when you get off to a good start, you just want it to continue as long as possible," said Defoe.
"I missed three games. It happens in football, players get injured. But if you miss three games and that changes the fact that you could, I don't know, go to a tournament, that's crazy."
Regarding the possibility of England selection, Defoe admitted he just wanted to let his performances do the talking.
"I don't feel like I need to sell myself to anyone because I'll just let my football do the talking," he added.
"I've done that since I made my professional debut at 17.
"I'm sure the manager (Rot Hodgson) knows what I can do."
