Chesterfield have agreed a fee with Leeds United over the sale of defender Liam Cooper.
The 22-year-old centre half has opened talks with the West Yorkshire giants.
Cooper looked set to join Leeds at the start of the month but talks broke down after the two clubs could not agree over a fee.
Leeds’ previous final bid is understood to have been £475,000 but the Spireites are said to have placed a value on the defender much closer to £1million.
It is thought that Leeds have tabled a bid in the region of £750,000 on this occasion.
The Whites reportedly see Cooper as a replacement for Tom Lees, who they allowed to join Sheffield Wednesday earlier this month.
