Townsend, however, is hoping the reported Sunderland signing doesn't play against his old club, as the Tottenham man knows first-hand what the 32-year-old is capable of in front of goal.
Indeed, Townsend is excited to see Defoe again but is hoping the 'fantastic' striker isn't around to do any damage to Spurs tomorrow afternoon.
“Jermain is a fantastic character who served this club well. On a personal level, it would be great to see him again and great for the fans to see him back here again. But on a professional one, I hope he doesn’t play against us," the Spurs winger is quoted as saying.
“Knowing him like I do, he is always hungry to get out on that pitch and score goals, whether it is in England or Canada. He is always hungry and he always strives to score goals."
Sunderland will no doubt hope Defoe can solve their goalscoring problems, with the Black Cats having scored just 18 goals in 21 Premier League game so far this season. That lack of goals has left Gus Poyet's side 16th in the table, although they are only two points off 12th.
Tottenham, meanwhile, sit in sixth - three points off fourth-placed Manchester United.
