It has been reported that Big Sam has offered £2million in an attempt to sign the Swede, but Appleton says the club will be sticking tightly to their asking price.
Appleton said: "Nothing is happening at the minute.
"I was made aware of a bid that was put in before I took the reins but it is way below the value we see him at.
"Until a bid reaches the valuation we think it should be, there is not a conversation."
