Arsenal boss Arsene Wenger stated earlier on Friday that the Welsh winger should stay in the Premier League, and Villas-Boas is in full agreement.
"It's extremely respectful. We have the best league in the world, in my opinion. For a player to develop to his full potential, it can be done perfectly in this league. Gareth has that in mind regarding Spurs and this league," Villas-Boas said at a press conference. "We don’t want Gareth to go away under any circumstances. I've told you in the past that our chairman is very difficult to deal with. We have to hold on to our best players to achieve our objectives.
"He has proved his quality in different fixtures against different opposition. He's going to be a major threat. You can't allow him any kind of space. He upsets opponents with his pace, power and technique. On this form he can continue to be decisive.
"I think he’s very down to earth. He’s a very human person."
Recent showings have sparked comparisons of Bale to players like Real Madrid star Cristiano Ronaldo, with Bale displaying supreme athleticism and a knack for the highlight-real goal en route to lifting Tottenham to third place in the Premier League.
"Comparisons are going all over the place," Villas-Boas said. "The level of form of the player means people are recognizing he’s world class. Merit is due where it’s due and I think Gareth is showing that level of form. Players like [Lionel] Messi have won titles, you have to win trophies and our aim is to do that.
"All of us have weaknesses one way or the other but the player is enjoying his football like he never was before. When you are at this level your weaknesses tend not to expose so much."
