Blackpool chairman Karl Oyston has told Derby County he is 'not interested' in discussing a deal for Shaun Barker.
Derby have failed in two attempts to sign the full-back, returning with a £400,000 bid after an initial swap deal involving Liam Dickinson was rejected.
The Rams were waiting for Blackpool to resolve their managerial situation before deciding whether to increase the offer, with Ian Holloway having been installed at Bloomfield Road last week.
However, Oyston is determined to keep Barker at the club and hopes the defender, who has a year left on his contract, will be part of Holloway's squad next season.
"It is true that we have turned down a bid for Shaun," Oyston told the Blackpool Gazette. "We are just not interested in talking to them at all.
"We have told them that what they have offered is not acceptable, and we don't want to swap any players.
"Particularly now we have a new manager it is vitally important that we keep our better players together and players that are fundamental to where we have got and keeping us in here."
Asked if Barker would still be at the club next season, Oyston replied: "I am hoping so. That's out of my hands isn't it?
"But what is in my hands is the current situation and we've told Derby that we are not interested in their offer and we've turned it down."
