Aston Villa boss Paul Lambert says striker Darren Bent is not for sale ahead of the close of the transfer window.
It is understood Saphir Taider is set to leave Southampton just three weeks after arriving on a season-long loan.
Sunderland have agreed a fee with Turkish side Bursaspor for France Under-21 midfielder Alfred N'Diaye, Press Association Sport understands.
Black Cats officials flew to Turkey with an improved offer after their initial bid, said to be in the region of £2million, was turned down.
Combative 21-year-old N'Diaye started his career with French club Nancy before moving to Bursaspor in July 2011.
N'Diaye is believed to be flying to the north east for a medical and to discuss personal terms. If confirmed, he will become boss Martin O'Neill's first signing of the January transfer window.
