TMW says Forest launched a late bid to sign the Italy midfielder before the window slammed shut last night.

Inter management had accepted Forest's offer, while Frattesi also had approved the move.
However, with contracts about to be exchanged, Chivu blocked the deal, insisting Frattesi could not leave.
The Romanian held face-to-face talks with Frattesi last week where he assured the midfielder his playing chances would improve over the second-half of the season.
Good to his word, Frattesi was handed a start by Chivu for the weekend's win at Cremonese.
