Dutch club Heerenveen insist they will not let striker Alfred Finnbogason on the cheap.
The 24-year old Iceland international is a target for Scottish champions Celtic but Heerenveen sporting director Gaston Sporre said he will only depart if the club receives a considerable offer for his services.
"He's good for at least 20 goals a season for us and we won't sell him for a reduced fee," said Sporre.
"If we get a concrete offer for him we will negotiate, but our aim is to keep him here at Heerenveen. He hasn't told us he is unhappy or asked for a transfer. We will wait and see."
Since arriving at Heerenveen from Lokeren last summer, the £5million-rated Finnbogason has scored 31 goals in 37 matches in all competitions.
