Villas-Boas, who worked as a scout for Mourinho at Porto, Inter Milan and Chelsea, recently claimed that he has no regrets over cutting ties with his compatriot.
While initially stating in today's news conference that he did not want to discuss his relationship with Villas-Boas, Mourinho has suggested that the 35-year-old was childish to talk to the media about their rift.
"I don't care what he says," insisted Mourinho. "I'm not here to do that. I'm not interested. I managed a Champions League final against a manager who was important in my career and taught me to grow up and I did it in a professional way, and that is a way you have to do it.
"I have had so many assistants in my career. I was always an open book to them and with the coaches in the academy. Will I go for a glass of wine with him? When people invite me I always go. I never refuse."
The two managers will go head to head tomorrow afternoon when Chelsea travel to White Hart Lane.
