The Togo forward has yet to start a match for Spurs this season having finished his loan campaign last year as the team's top scorer.
Rumours had suggested that the boss had fallen out with the striker, but Villas-Boas claims that it has been Adebayor's injury troubles that have kept him out of the side.
"We're quite happy with his attitude," Villas-Boas said. "He had an injury which took him out for six games and then another injury took him out for two games. We have the injury records if you want to look at them.
"From the 11 that we've played, I think he's been out for eight of them and he wasn't here at the start of the season.
"In the games when he was available he showed the quality striker that he is. We have no doubts whatsoever. We have him fit now and hopefully ready for the next upcoming games. We know his ability."
Adebayor moved to White Hart Lane for £5m in the summer.
