Championship Sunderland have completed the deadline day signing of Callum Styles from Barnsley on loan until the end of the season.
The 23-year-old Hungary international has joined the Black Cats with an option to buy included in the loan deal.
The former Millwall man has made 124 Championship appearances in his career and joins a Mackems side, who currently sit seventh in the second tier just one place outside the play-off positions.
Speaking about the transfer, Sunderland sporting director Kristjaan Speakman said: “Callum is an interesting player, who has the ability to play on the left side of central midfield or slightly wider in a full back or wing back role, so we feel his quality and flexibility will be a real benefit to us throughout the remainder of the season.
"Having reached an agreement in principle last week, we had an unavoidable delay due to Callum’s illness, but after reviewing his progress, we are now delighted that he’s here and we look forward to his imminent return to action.”
