The England striker has netted five times in the Premier League this season but the White Hart Lane boss feels that there is scoring potential yet to be unlocked elsewhere in the side.
Regarding Tottenham's current situation, Villas-Boas told the Daily Mirror: "We have Defoe on five goals, obviously, but the team has a lot of goalscorers in Gareth Bale, Clint Dempsey and the central defenders who contribute in that aspect as well.
"To have diversity is important and it shows we are not just relying on Jermain, although he is doing extremely well."

"Eight goals in five games is the type of goalscoring ability you want in your team - and we have Adebayor, who I'm sure will make a good run in the side after his injury setbacks," the Portuguese continued.
"We have considered playing Adebayor and Defoe as a pairing up front but we have found comfort in the system we have been using and it has taken us to fourth in the Premier League.
"It's something we can use in the future but we are comfortable with where we are at the moment."
Someone who wants to add to his goalscoring record is Tom Huddlestone, who revealed that he has not had a hair cut for a year and will not do until he ends his goalscoring drought - which has now lasted for 18 months.
Referring to the player's past struggles with fitness, Villas-Boas observed: "It's so good to see Tom make four games in 10 days - hopefully we can bring him back to the level he was and the expectation of the talent he can be."
