Southampton striker Sharp wanted permanently by Forest
Forest boss Sean O'Driscoll has admitted he would like to agree a deal for the 26-year-old.
"Everything has a price. But it is whether Southampton want to sell," said the man who was in charge at Doncaster when Sharp was signed.
"I am not sure, because we have not had that conversation.
"I'm not sure there are any fans in the country who don't like Billy Sharp."
