Bolton Wanderers boss Owen Coyle has confirmed the club have agreed a fee with Chelsea for defender Gary Cahill.
The England international centre back has been the subject of strenuous transfer speculation in recent months after the Trotters rejected summer bids from Arsenal and Tottenham Hotspur for the player.
But, with the 26-year-old unwilling to sign a new deal at the Reebok Stadium and his current contract set to expire at the end of the season, his future always appeared elsewhere in the Barclays Premier League.
It's reported that the fee is in the region of £7 million, and providing personal terms can be agreed, Cahill will join compatriot John Terry at the heart of the Blues' defence as Alex prepares to leave Stamford Bridge in the opening month of 2012.
"There has been a fee agreed between the clubs and we have now given Gary's representatives permission to speak to Chelsea. That is where we are with it," said manager Owen Coyle.
"We obviously have a game tomorrow and I have said to Gary that he has to be focused on giving everything for Bolton Wanderers, because he knows Bolton Wanderers has been terrific for him just as much as Gary has been for us.
"That is why they have representatives - to sort that out - and whatever January 1 brings, it will bring."
Cahill moved to Lancashire from Aston Villa in 2008, and has significantly improved during his three-and-a-half years with Bolton following the £5 million move.
He will however be leaving a club who sit 19th in the table, and also hold the worst defensive record in the English top flight.
