Despite his history with Arsenal, Adebayor won the affection of Spurs fans last year, topping the club's scoring charts with a return of 18 goals in 37 matches while on loan from Manchester City.
Since the 28-year-old signed a permanent deal at White Hart Lane last summer, he has been unable to find the net as regularly, however.
Adebayor has scored three goals in 24 games so far this term, and his performances have lacked the energy and passion he showed last season, leading some supporters to question the striker's commitment to the cause.
Spurs boss Villas-Boas shirked at that claim on Wednesday, and tipped the former Real Madrid hitman to find his scoring boots soon - starting with the Europa League last-32 second leg at Lyon.
"He can still be the player we saw last season," said the Portuguese, who has to start Adebayor as Jermain Defoe is out with an ankle injury.
"We're trying to unlock the best out of the player. Last year shows as an example for what we're trying to get out of him.
"Strikers live off goals and we're doing everything we can to try and unlock his full potential."
