The striker recently returned to training with the Premier League club following a three-month absence on compassionate leave.
Reports have suggested that Spurs could let the 29-year-old move on a temporary deal, but Villas-Boas claims that a switch is unlikely.
"At the moment he's come back into the team to train, which he hasn't done since the Hong Kong trip, so at the moment we are monitoring how the player develops his fitness and challenges for his place in the team," he is quoted as saying by Sky Sports News. "We're not considering anything."
Adebayor's last competitive appearance for Spurs came on the final day of last season.
