The Tykes are keen to strengthen their goalkeeping unit this month and provide further competition for vice-captain Adam Davies and Nick Townsend.

Listen to the latest Transfer Talk podcast where Ross Barkley's move to Chelsea and Philippe Coutinho's Liverpool future were among the topics discussed.
Should he move this month it will be the first time the 28-year-old has done so for a transfer fee. After spending time in non-league football following release by Huddersfield as a trainee, Eastwood played for Bradford City.
He spent the 2010-11 season at Oxford but did not make an appearance before spells with Halifax and Portsmouth.
