Hull are confident of keeping defender Charlie Hughes at the MKM Stadium.
The Tigers have rejected two bids from Championship rivals Coventry, the last being £7m, for the 21-year-old.
Hull sold Jacob Greaves to Ipswich for £17m last summer and it is expected any offer for Hughes would need to eclipse that to even be considered.
But the Tigers are also under a transfer embargo and unable to sign players for a fee, meaning they would not be able to reinvest the money for a replacement, leaving them determined to keep Hughes.
He joined Hull from Wigan last summer as a replacement for Greaves - winning the club's Young Player of the Year award - and has made 28 appearances, including Saturday's opening 0-0 draw at Coventry.
