Sunderland have wasted no time in addressing problem areas in the January transfer window.
Lee Johnson's side have already completed the signings of Trai Hume, Danny Batth and Patrick Roberts, with Tottenham Hotspur's young winger Jack Clarke the latest name being linked with the Wearsiders.
Clarke burst onto the scene at Elland Road under the tutorage of Marcelo Bielsa, before moving to White Hart Lane for £10million back in 2019.
