Andre Villas-Boas is convinced that Jose Mourinho wants to manage in the Premier League once again.
The Tottenham manager was part of Mourinho's staff at Porto, Chelsea and Inter Milan before branching out into management himself.
Mourinho appeared to indicate his desire to work in England again following Real Madrid's defeat to Borussia Dortmund in the UEFA Champions League earlier this week.
With Rafa Benitez in charge at Stamford Bridge only in an interim capacity, speculation has been rife that Mourinho could return to Chelsea just under six years after he left the club.
"He obviously wants to come back to England, whether he has a club aligned or not, we never know," said Villas-Boas.
"It's extremely unlikely when someone makes it that public that something is not set out already but he is a great addition to the Premier League.
"He has a wonderful history in this league and I think it will be spectacular to have him back."
