Aston Villa are expected to complete the £3million signing of Henri Lansbury by Friday.
Nottingham Forest have finally given the green light for the midfielder to move to their Sky Bet Championship rivals, Press Association Sport understands.
Lansbury is out of contract in the summer but the transfer has dragged on because of the takeover saga which has been ongoing at the City Ground.
The takeover fell through last week and the Reds sacked manager Philippe Montanier at the weekend.
Villa boss Steve Bruce admitted last week he would be prepared to wait for Lansbury if Villa failed to complete the move this month but is set to get his man in the next 24 hours.
Ex-Arsenal trainee Lansbury, who joined Forest from the Gunners in August 2012, has scored six goals in 19 appearances this season.
He has not played since suffering a hamstring injury before the 3-0 loss at Derby in December.
Villa are also interested in Barnsley's Conor Hourihane and Middlesbrough's Jordan Rhodes with Robbie Brady from Norwich also attracting attention from Bruce, who he worked with at Hull.
