There've been a lot of names mentioned here, and I amn't exactly qualified to comment on all of them, but for those I do watch regularly or occasionally, most are far from Juve's standard.
Graveson:
was mentioned in passing by a Dane. I think he was half-joking, but some of you aren't. Trust me, the guy's a tank, with the stamina of a bull, but he looks workman-like even in Everton's extreemly workman-like midfield.
Gerrard:
Has a lot of potential, but he's not in the class of the top defensive mids just yet. Has disiplinary problems. Has been known to enjoy the odd tipple, or indeed bottle, before matches. Would take stupid money (as in like E50m) to even get Liverpool to let one of their prized youth products to leave. Would be extreemly hard to convince even then that Juve, or even Italy, was the place for him. Just isn't worth all that hassle.
Vieira:
Is as good as they get, and would definately replace Davids - he'd be an improvement. I heard a few months ago that a couple of Arsenal players had signed new contracts, Wenger and Henry lead the pack, but I don't remember whether or not Vieira was involved. He's certainly made the right noises about signing now. May not see Italy as a nice place to return to, give the problems he had with Milan, and during away games there with Arsenal. May not consider Juve better than MAdrid, who are likely to be very interested too, after their sale of Makelele.
Hargreaves:
is an average player, versitile, certainly worth havign in the squad, but his potential is great enough that Bayern are unlikely to let him go on the cheap, which makes him a dodgy investment.
Xavi Alonso:
I've unfortunately not seen him play, but Spanish friends rated him higher than Makelele, who was mentioned here. Young. Prpbably not cheap though.
Makelele:
Sure, go right ahead and make a bid that Roman Abrahmovic can't afford to refuse...
