Robins put hefty tag on Cox's head
The Scottish champions have been linked with a move for the prolific forward, as well as teenage defender Sean Morrison.
Town chairman Andrew Fitton told the Scottish Daily Mail: "We value Simon at £2.5million. We have made no secret of what we think his value is.
"I'm not surprised Celtic's interest is not going away because Simon is a class player.
"We have had two approaches from clubs but nothing in writing."
Meanwhile, Shunsuke Nakamura says he will play through the pain barrier in a bid to help Celtic win the title.
The Japan international - tipped for a return to his homeland in the summer - has been troubled by a groin problem but is determined to face Hearts on Sunday.
He told the Daily Record: "I still have a lot of pain in my groin and I will have to take tablets all week to make sure that I can play for as long as possible.
"I'm desperate to play in the game because it is such a huge match for Celtic."
