Doncaster chairman John Ryan would sell prolific striker Billy Sharp for £3million in January. Sharp's brace in the 2-1 victory over Leicester took his tally to nine goals in 15 Championship appearances this season and he has a string of admirers.
"When the window opens on January 1, Billy's contract with Doncaster Rovers will include a release clause priced at exactly £3million.
"Lots of clubs are circling. Southampton and Ipswich made previous bids. Anybody who matches that new figure can talk to Billy.
"Obviously, we don't want to lose the lad at this vital stage when we are fighting to retain our Championship status.
"I've given my word to Billy, though. We have a gentlemen's agreement and any final decision on a move is down to Billy himself." Ryan said: "I don't know whether we can keep Billy here. There has been a lot of loose talk and idle chatter surrounding the lad, so I want to set the record straight once and for all.
