The Portuguese hailed his former club and his successor, Roberto Di Matteo, after the Blues defeated Bayern Munich on penalties to win Europe's premier club competition
The Portuguese was sacked by the Blues in March after a troubled time in west London, enduring a difficult relationship with some of the more experienced members of the squad.
He was replaced on an interim basis by his assistant, Roberto Di Matteo, who has since led the Stamford Bridge side to a European and FA Cup double.
"The biggest honour is to win the Champions League. Congratulations to Di Matteo and the players," the former Porto coach told RTP.
Despite turbulent spell at Chelsea, Villas-Boas has recently been linked with several top jobs, including the vacant Liverpool manager’s role as well as at Inter in Italy.
However, the 34-year-old refused to disclose his next move, and says that he will have to weigh up his options before accepting his next challenge.
"I am still choosing the right project and such a decision will take as long as necessary,” the Portuguese said.
