Birmingham City manager Chris Davies is actively shaping his squad during the January transfer window, with a move for Sunderland's Luke O'Nien now appearing a more distinct possibility.
Defensive Departure Creates Opportunity
The path for a potential new arrival has been cleared following the confirmed departure of defender Eiran Cashin. His loan spell from Brighton and Hove Albion has been terminated early, with the player now joining Championship rivals Blackburn Rovers on a temporary deal until the season's end.
This move frees up both a squad place and financial resources for Birmingham, who have already signed left-back Kai Wagner from Philadelphia Union this month. The club has until the deadline of Monday 2nd February 2026 to finalise any further business.
Luke O'Nien Emerges as a Target
With room now available, Birmingham are reportedly among a group of clubs, including West Brom and Coventry City, showing interest in Sunderland's Luke O'Nien. The 31-year-old has found first-team opportunities limited at the Stadium of Light under manager Regis Le Bris in recent weeks.
Despite being under contract with Sunderland until the summer of 2027, his need for regular football could prompt a winter move. O'Nien has been a loyal servant to the Black Cats since joining in 2018, making 314 appearances and scoring 23 goals, and played a key role in their ascent from League One to the Premier League.
Why O'Nien Could Be a Smart Signing
The potential acquisition of Luke O'Nien represents a calculated gamble for Birmingham City. His primary value lies in several key areas:
- Promotion Experience: He possesses direct experience of achieving promotion, a valuable asset for Birmingham's play-off ambitions.
- Versatility: Capable of playing in defence or midfield, he offers crucial cover and tactical flexibility to manager Chris Davies.
- Proven Pedigree: With over 300 games for Sunderland, he brings a wealth of Championship and higher-level know-how.
Birmingham, who won the League One title last season, are seeking greater consistency in their bid for the play-offs. Their recent 3-2 victory over Coventry City – with a brace from Marvin Ducksch and a goal from Liverpool loanee Lewis Koumas – was a step in that direction.
For O'Nien, a transfer could reignite a career currently stalled on the bench, offering a fresh challenge at a club with clear ambition. As Birmingham prepare for an FA Cup tie away at Cambridge United this weekend, their work in the transfer market appears far from over.
