Wigan manager Paul Jewell has warned Rangers their £750,000 offer for Lee McCulloch came nowhere near the Latics' valuation.
However Wigan have dismissed the bid from Ibrox as 'insulting', indicating only a substantially increased sum could tempt them to sell the 28-year-old.
Jewell said: 'Rangers have made an approach for Lee McCulloch, but the offer they made can only be described as derisory. In fact, it's insulting.
'They offered us £750,000. He is a player we paid £700,000 for when we were in the old Third Division. Since then he has gone on and become a Championship player, a Premiership player and a full international.'
Jewell stressed that the Scotland forward, who is contracted to Wigan until summer 2009, would stay at the JJB Stadium unless a large seven-figure offer came in.
He added: 'If Rangers or any other club think we would sell an established player and international for such a paltry sum then they are sorely mistaken.'
