He'll offer cover - I'd rather have him in my squad than O'Shea, Evans, or Gibson who were part of a Premier League winning squad. And he will help the homegrown quota. Also, while his form did fade with Sunderland's as a whole, earlier last season he was outstanding at times, even had Bale largely in his pocket one game, and scored one of the goals of the season against Chelsea. Consider that plus us having the best manager in the entire league to get something out of a defender (ask Micah and Lescott), then he could be a good player for us still.
