Atletico Madrid star Diego Godin has admitted he would be interested in a move to Chelsea should the club be interested in signing him.
A move did not materialise in the off-season, but with Chelsea's defensive problems mounting following three defeats in their last four Premier League games, Villas-Boas will surely strengthen that department in January.
And Godin has opened the door for a move, if the Blues decide to make an offer.
"If there is interest from Chelsea, I will study it," the Uruguay international told Goal.com Spain.
Godin, whose contract runs until June 2015, is a key member of the Atletico side and will command a transfer fee around £20m.
