Personally, I still think he's going to sign for us. There have been to many rumblings and signs pointing in that direction. Especially the Mourinho press conference yesterday, and the fact that people from the social media staff are following him etc.
That said, I do think it is starting to drag out quite a bit. I know he's on holiday, but that really doesn't stop an announcement from happening. Especially Juventus must be very interested in just getting this saga over with, so there's absolutely no reason why they shouldn't just have announced a deal subject to medical if the deal was in fact done.
And to be fair, if this deal somehow falls through, it's not like it's the first time in history that a deal at this stage has collapsed.
