Rangers manager Ally McCoist has warned West Ham they will not get Nikica Jelavic on the cheap.
The 26-year-old has been linked with Liverpool and more recently the Hammers after netting 17 goals in 31 games this season.
It is a record that has seen Rangers place a high premium on the Croatia international's value, while the speculation around him continues to grow.
English Championship side West Ham have so far been frustrated in their search to land a striker after Huddersfield rebuffed their bids for Jordan Rhodes.
And McCoist maintains that if they want to lure the in-form marksman to Upton Park, they will have to stump up the cash and dismissed rumours they had already made a bid.
"They have not made an official bid," he said.
"The reported amount would not be enough to meet the demands of the owner; £6million is not nearly enough."
