Chelsea are being linked with a January raid on Bolton Wanderers defender Gary Cahill.
The Daily Mail claims Blues boss Andre Villas-Boas has highlighted the England international as a player who can shore-up the club's shaky defence, with an £8 million price-tag placed on Cahill's head.
With a contract at the Reebok Stadium set to expire in the summer, 'AVB' is hoping to secure a cut-price deal for the centre back, although interest from Arsenal and Tottenham Hotspur means the fee will remain relatively high for a player who has six-months left on his current deal.
Chelsea appear to be a club in turmoil after three defeats in four matches, with two losses at Stamford Bridge suggesting all is not well in west London.
With the race row continuing to linger over club captain John Terry and doubts starting to surface over the Barclays Premier League credentials of David Luiz, Villas-Boas is expected to turn to the transfer market at the next possible opportunity.
A defender is top of the agenda for Chelsea, and whilst players from across Europe have been mentioned, Cahill would provide experience at the highest level in English football.
The fee is not a problem either, given the funds at the Chelsea manager's disposal under owner Roman Abramovich, and a move is expected at the beginning of 2012.
