Signing for as rotational option despite his sadly broken body, would be nice (understatement lol). His age is NOT an issue, since this would be for 1-2 seasons at best, sadly though him being near cripple is though.
If you can get near 2 dozen games out of him for a full season, it would be a successful enough (and would instantly be our best defender). But I somehow doubt his body would hold. But anyways, for sheer nostalgia of having the best defender I ever seen in our shirt, I would say yes. I cant describe how glad I would be to see this defending magical genius playing even one game for Juve.
