Celtic boss Ronny Deila says keeping his best players will take priority over acquisitions in the transfer window.
Chelsea striker Fernando Torres is understood to be set for a return to Atletico Madrid, according to Sky sources.
Barnsley have announced a press conference for 3pm this afternoon where they are expected to confirm Danny Wilson as their manager for a second time.
The 53-year-old, who was sacked by Sheffield United in April, led the Tykes to promotion to the top flight for the first time in their history in 1997 during his first spell at Oakwell.
He can also count Sheffield Wednesday, Bristol City and Hartlepool among his former clubs.
The Reds have been searching for a new boss since parting company with David Flitcroft at the end of November and have tasked Wilson with pulling the club away from the foot of the Sky Bet Championship.
Wilson's first game in charge will be Saturday's Yorkshire derby against Leeds at Elland Road.
