Spurs' poor scoring record in the league cost last season them a place in this year's Champions League.
Adebayor scored on his debut in Spurs' 2-0 win at Wolves on Saturday - Defoe, who netted just four Premier League goals last term, was also on the scoresheet at Molineux.
"He is brilliant. I was looking forward to it (playing with him) even before he came," Defoe told Spurs TV Online.
"There was a lot of speculation that he was coming and I just thought to myself 'please let it happen' because he's a great player.
"He's quick, he can head it, he is strong and he is a good finisher.
"He can do everything. Him being there freed me up a bit because it allowed me to drop deep, get on the ball and beat players so it was good."
