Spurs will be guaranteed a top-four finish and a return to Europe's elite competition if they win their remaining five Premier League games.
And, according to Villas-Boas, PFA Player of the Year contender Bale will resist offers from elsewhere if Champions League football is on offer at White Hart Lane.
"That's the information that I have from the club," the Tottenham manager said.
"The club is committed to keeping the best assets. That's the only way that we
can ensure that we are in the top four every year.
"Gareth is part of that project bearing in mind that he has been amazing this season. Hopefully we can develop him to a greater extent."
Bale signed a new long-term contract last summer, and recent newspaper reports claimed it would take a fee in excess of football's £80m transfer record to persuade Spurs to sell.
