Celtic manager Ronny Deila insists Virgil van Dijk does not want to leave the Scottish Premiership leaders in January.
Celtic boss Ronny Deila says keeping his best players will take priority over acquisitions in the transfer window.
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.
