The Welshman has been linked with a big-money move away from Spurs, although reports on Friday suggested he was close to signing a new improved contract worth £170,000-a-week.
"I'm not sure (about whether Bale is close to signing a new deal), our interest is for the player to continue here and I've made that very clear," said Villas-Boas.
"Whatever is happening, the idea is for the player to be here next season.
"I have said this numerous times. We are pretty confident we will be able to keep him."
