Talking to the media after Sunday's match at White Hart Lane, Villas-Boas said that people insult his integrity and singled out Ashton.
He continued: "A couple of people insult my integrity, my human values, my professionalism and one of these people is sitting over here.
"It insults the success that I have achieved in other clubs and I don't think it's fair. I think it's a lack of respect and an attack on a person's integrity."
Ashton, Sportsmail's Football News Correspondent, then asked the Spurs manager what he thought was "personal" about the recent criticism of his team.
"You can easily understand. I don't need to explain. I think you have always chased people, you attack people," Villas-Boas responded.
"You don't attack them by the front, you attack them sitting when you write. You attack integrity, you attack competence, you attack the integrity of the person, their human values and you don't even know that person."
Sunday's draw means that Spurs are ninth in the league.
