Nottingham Forest manager Steve Cotterill says it is "ludicrous" that so many of his players are out of contract at the end of the season.
Cotterill told BBC Radio Nottingham: "Desirable players going out of contract is ludicrous. I don't understand what has happened.
"If I could have [sorted new deals], I would have done before Christmas."
He added: "Players getting into the last year of the contracts is not an ideal situation - let alone when there is five weeks of the season left.
"One of the first things I said when I came in was that players needed to be tied down on contracts now and we haven't been able to do that for one reason or another."
