Cahill joins Chelsea
Chelsea have confirmed the completion of the protracted signing of Gary Cahill from Bolton.
The England defender, 26, has become manager Andre Villas-Boas' first January recruit.
Cahill's capture, for a fee Press Association Sport understands to be around £7million, followed a fortnight of wrangling over the player's personal terms.
The parties reportedly settled on wages of £80,000-per-week on Friday, £20,000 less than Cahill was said to be demanding.
The player then travelled to London to undergo a medical and watched his new club's 1-0 Barclays Premier League win over Sunderland on Saturday. Chelsea were once again far from convincing at the back and supporters will be hoping Cahill can provide the much-needed solidity for which they were long renowned.
The player told his new club's official website, www.chelseafc.com: "Chelsea is a massive club, it is a club that looks to win trophies season in, season out and it is a big opportunity for me to be a part of that.
"Opportunities like this, you can't turn down."
Despite being part of a Bolton defence among the worst in the Premier League this season, Cahill has performed well alongside Chelsea captain John Terry at international level.
There were no shortage of admirers for the defender, with Arsenal seeing a bid rejected last summer and Tottenham also going close to landing him.
But Chelsea were the only serious January transfer window bidders, with Bolton opting to cash in on a player in the final six months of his contract.
