Paul Heckingbottom bolstered his side late on Transfer Deadline Day (31st January) by bringing in three new players as the Reds aim to avoid a relegation battle in the Championship.
The first signing to be announced was the long-awaited move for Austrian midfielder Christoph Knasmuller from Admira Wacker. The 25-year-old signed a two-and-a-half-year deal.
He started his career with Bayern Munich before moving onto Inter Milan, where he failed to make a first team appearance. He was then snapped up by German side FC Ingolstadt.
His spell with homeland side Admira was a fruitful one for Knasmuller, playing 104 times and scoring 38 goals.
The next man through the door at Oakwell was experienced centre-half Matt Mills, who joined the Reds after his release from Nottingham Forest, on a short term deal until the end of the season.
31-year-old Mills becomes the oldest member of the Reds first team squad and serves as a direct replacement for Angus MacDonald, who joined Hull City on Wednesday.
Mills began his career with Southampton, before moving onto Manchester City, where he made 2 appearances and spent time on loan with Colchester and Doncaster, who signed him permanently in 2008.
Since then, he has represented Reading, Leicester, Bolton and Nottingham Forest, racking up almost 400 appearances at Championship level.
The third signing at just after 11pm needed no introduction, as he had already signed for the Reds in August before seeing his move fall through.
21-year-old Oli McBurnie joined on loan from Premier League side Swansea City until the end of the season.
McBurnie has appeared 11 times for the Swans in the top flight this season, and has been allowed to leave the Liberty on loan after the capture of Andre Ayew.
Meanwhile, young striker Jacob Brown was allowed to move on loan to Chesterfield, joining Dylan Mottley-Henry, who had joined the Spireites in a similar move earlier in the day.
