Tudor isn't the defender he once was, but even at Siena he still seems to display a lot of the "air ball" talents that Juve so woefully lacked against Pool recently.
Is it enough to warrant a return? I'm not so sure. If there are players we want to have to fill specific situational roles, I'd rather see us choose them on the basis of our weaknesses against an opponent like Milan -- e.g., creative midfield a la Kaka, Seedorf, Pirlo. Camo has done very well this season, though particularly on the wing. But Nedved has been out of form. And most importantly: the "Blasi" spot, IMO, has been an Achilles Heel for us.
