Chelsea continue to be linked with a £7 million move for Argentine international Lucho Gonzalez.
The Marseille midfielder has been linked with a move to Stamford Bridge on a number of occasions, and reports in France now claim the Stamford Bridge outfit are ready to up their pursuit of the player.
A long-term injury to Michael Essien is thought to have increased Andre Villas-Boas' need for a player in the central midfield position, with the Ghanaian international set to miss six months of the Chelsea season with a serious knee problem.
Despite technical director Michael Emenalo's comments that the injury will not affect the Blues' moves in the transfer market, Chelsea have been linked with a handful of players in recent days who could fill in for the player in the same position.
Scott Parker, Cheik Tiote and Daniele De Rossi have all been speculatively linked with a move to west London, whilst playmaker Luka Modric is also thought to be on the Chelsea radar.
30-year-old Gonzalez is tipped to make a Ligue 1 exit this summer, although a move to Malaga fell through last month as L'OM look to offload the player.
Villas-Boas' relationship with the player stems back to his four years at Porto between 2005 and 2009, with the recently appointed Chelsea boss an admirer of 'El Comandante'.
Brought to the Stade Vélodrome for €18 million back in 2009m Didier Deschamps would have to take a loss on the player were he to move to Chelsea in the window.
