Hull City have insisted Cameron Stewart is 'not for sale' after Leicester City made an improved bid to sign the winger.
Sky Sports revealed on Sunday that the Foxes had upped their offer for Stewart to £1.5million after seeing a bid of £1million turned down last week.
Leicester's former Hull boss Nigel Pearson is keen on a reunion with Stewart, but the Tigers have rejected the revised offer from their Championship rivals.
And Hull's head of football operations Adam Pearson has called on Leicester to stop 'messing around' after stressing Stewart will not be leaving the KC Stadium.
"Cameron Stewart is not for sale, end of story," Pearson told the Hull Daily Mail.
"We don't want to sell Cameron and the player doesn't want to go, so Leicester are wasting their time.
"We've told them to stop messing around. If this is designed to unsettle the player, it won't work.
"We're treating it with the disdain it deserves and my advice to them would be to move on to other targets.
"None of the players we want will be leaving the club this month.
"Cameron knows where he will be playing his football. He is not interested in leaving and we're not interested in selling him."
