Andre Villas-Boas keen on Lazio defender Stefan Radu

Chelsea manager Andre Villas-Boas has stepped-up his pursuit of Romanian international defender Stefan Radu.
The Lazio full-back was first linked with a move to Stamford Bridge over the weekend, and fresh reports in Italy claims the Blues have taken their interest a step further.

Tuttosport reports that Chelsea are ready to make a move when the January transfer window opens, and that Villas-Boas has already made contact with the player's agent, Victor Becali, over a possible move.
Barcelona boss Pep Guardiola is also said to be an admirer of the 24-year-old, who has impressed in Serie 'A' after moving from Dinamo Bucharest in 2008.

Chelsea have one of the world's best left backs in the shape of England international Ashley Cole, but lack strength-in-depth at the position and could be vulnerable if the player were to get injured.Aware of the problem, Chelsea will be monitoring Radu's contract situation closely as he stalls on a new deal at the Stadio Olimpico.
