Chesea defender target Stefan Radu could be leaving Lazio in the January transfer window, according to the player's agent.
TalkSPORT claims the Blues have been tracking the left back after failing to secure the services of Porto's Alvaro Pereira, with reports in Italy going on to suggest Andre Villas-Boas could make a move in the New Year.
The 24-year-old Romanian international signed a new five-year deal in the Eternal City in June, but agent Victor Becali refused to rule out a move when speaking to radio station Mana Mana as the Chelsea rumours circulate.
"If something interests us in the coming months then we will talk it over. Stefan has renewed his contract but in football you can never take anything as certain," said Becali.
"I have read that big clubs in England, Spain and France are interested but at the moment I have not spoken to anyone about it."
Villas-Boas' pursuit of a player in the left back position is predominantly thought to be as a back-up for Ashley Cole at Stamford Bridge, with the England international cemented as the first choice for Chelsea as part of their back four.
However, the Portuguese manager is hoping to provide some competition to the 30-year-old, and former Dinamo Bucharest defender Radu appears to be a realistic possibility for Chelsea.
