Kristjaan Speakman has reviewed Sunderland's January transfer window, and says the Black Cats are still looking at adding free agents.
The Black Cats signed six players in the window - Trai Hume, Danny Battth, Patrick Roberts, Jay Matate, and Jermain Defoe, along with taking Spurs forward Jack Clarke on loan - and let several leave, with Tom Flanagan, Aiden O'Brien, and Denver Hume among the departures.
Sporting director Speakman revealed that the Black Cats had tried and failed to bring in another centre-back on deadline day, and also had a number of bids for player fail to come to fruition towards the end of the window.
