Bolton Wanderers boss Owen Coyle is prepared to sell Gary Cahill this summer.
Chelsea, Arsenal, Liverpool and Manchester United are all interested in the England defender.
When questioned on the hard task of keeping Cahill this summer Coyle told Sky Sports: "It's not a task as such because if somebody comes in and its good business for the football club then it's something we have to look at.
"Wherever I've been I've never worried about that because if somebody comes in and it's the right fee or its good business. Ultimately you have to be fair with the player as well.
"What I do know if that is the case then we have to make sure that we've got targets lined up that can come in, replace whoever it is and look to take the club on and improve it."
