Chelsea have confirmed the signing of England international defender Gary Cahill.
The 26-year-old centre back moves to Stamford Bridge from Bolton Wanderers for an undisclosed fee, although general reports claim the deal is in the region of £7 million.
"Chelsea is a massive club that looks to win trophies season in, season out," he told the club's official website.
"It is a big opportunity for me to be a part of that. Opportunities like this, you can't turn down."
Owen Coyle admitted over the weekend that a deal was less than 48 hours away, with the Trotters resigned to losing their prized asset after Cahill confirmed he would not sign a new contract with the club.
Brought to the Reebok Stadium from Aston Villa for £5 million in 2008, the defender has proved to be one of the Barclays Premier League's most consistent performers in the position during his three-and-a-half years in Lancashire.
His home is now the capital however, and Cahill joins four international colleagues at Chelsea, including Three Lions skipper John Terry and full-back Ashley Cole in defence.
