Andre Villas-Boas insists he does not lose any sleep over his split with Jose Mourinho.
Villas-Boas and Mourinho will lock horns for the first time on Saturday when Chelsea visit White Hart Lane.
For seven years Villas-Boas worked under Mourinho as a scout at Porto, Inter Milan and Chelsea.
But after Mourinho rejected Villas-Boas' plea to move up to a more senior role, the 35-year-old decided to go his own way.
The move paid off as Villas-Boas enjoyed success at Porto, before going on to manage Chelsea and now Tottenham.
The pair enjoyed a good working relationship during their time together, but Villas-Boas insists he had to leave his mentor's side to pursue his own management career.
When asked if he regretted no longer being close to the Chelsea manager, Villas-Boas said: "I don't lose any sleep.
"Our break-up point was because I was full of ambition to give him something extra and I wanted further involvement from the job I was doing at that time.
"I felt I could give him much more. But he didn't feel the need for somebody near to him or in another position as an assistant, and because of that it was decided that it was time, after Inter Milan, to continue our careers [apart]."
The current state of the relationship between the two was probed on several occasions at Thursday's media conference. Would it be fair to say that Villas-Boas no longer considers himself friends with Mourinho, one reporter asked.
