With 11 days left in the January transfer window, BBC Scotland assesses squad needs across the Scottish Premiership. At Aberdeen, manager Jimmy Thelin faces a bloated squad of 28 players — the league's third-largest — after 13 summer arrivals and 14 departures. Thelin has publicly stated he needs to offload players rather than add more.

Celtic manager Brendan Rodgers has a settled starting XI thanks to Arne Engels and Kasper Schmeichel, but the bench is thin. Right-back Alistair Johnston faces an extended injury absence, and Greg Taylor is the only senior left-back, with Rodgers noting his minutes need managing. After receiving £22m for Matt O'Riley, funds exist for reinforcements, particularly a backup goalkeeper and right-back for Champions League duties.

Dundee manager Tony Docherty operates with the league's smallest squad at just 22 first-team players, losing Lyall Cameron for the season. With only five defenders, Docherty needs reinforcements in defence and out wide, recalling that key players like Cam Congreve arrived late last window.

Dundee United boss Jim Goodwin has signed 12 players but faces uncertainty over left-back Ross Graham's expected departure. Romanian international Adrian Mazilu has arrived, but he would be the sole left-back if Graham leaves. United also struggle for goals, managing just one in four games, with questions over whether Sam Dalby or Louis Moult can lead the line alone.
