JOIN USVillas-Boas was a member of the backroom staff when Mourinho was in charge of Chelsea from 2004-07 before following his fellow Portuguese to Inter Milan.
"There is no way you can avoid comparison. It is something that interests the media," Villas-Boas told the club's website on Wednesday after leaving Porto to sign a three-year contract with the Premier League club.
"(But) I didn't take the Porto job nor the Chelsea job because Jose made the same steps. They are two of the most sought-after clubs in the world and in the end I had the opportunity."
The 33-year-old acknowledged that he had experienced a remarkable rise up the managerial ladder after leaving Mourinho's backroom staff at Inter to take over as coach of Portuguese championship team Academica in October 2009.
"It is something that went crazy, there is no doubt about it," said Villas-Boas. "In two years we have achieved so many things and they were two very happy years.
"The important thing people have to reflect on is I don't see the game as a one-man show. I see the game as the getting together of collective ideas and good players."
Villas-Boas said he felt the time was right to break out on his own at Academica. "When a chance to coach happened when I was at Inter, I just felt inside me that I wanted to take on another role and face the challenge... so I left Jose," he explained.
"Coaching had not been an obsession and neither did I use Jose to arrive down that path. It was something that happened naturally and at the moment it is working out well."
