Bolton Wanderers boss Owen Coyle hopes to build his side around defensive duo Gary Cahill and Zat Knight next season.
Coyle is keen to hold on to both players, with Cahill in particular attracting interest from a number of bigger clubs.
"The two of them are outstanding centre-halves," Coyle told the Bolton News."I want to build a team around the likes of Gary Cahill and Zat Knight.
"If someone offers us as a football club something we can't refuse, then we'd have to look at that, we'd be crazy not to. But as a manager I want Gary here.
"People said to me prior to coming to the club that Zat had been in indifferent form, but he's been outstanding for me on a game-to-game basis.
"He's a leader and enjoys himself and that's the type of player I want at the football club."
