From what I have heard we sold him for 3m sterling pound. Anyway, I'll take your word since you are generally presice on this petty details.

.
Nonetheless, my belief is that if you have a young prospect who needs to gain experience and what them back in the future then you
loan them. As far as I am concerned co-ownership should only be used in instances where 1) risky talent and 2) purely looking to make investment.
We are a big enough club to fully take on risks involved in Micco, and he isnt exactly an unproven player. Why pay Fiorentina additional 5-6 millions in 2 years time to get him back when we could have just loaned him?
My suspicion is that Micco isnt coming back, and if he does well, I reckon we will simply sell half of his contract rather than buying other half back. I am fine with that as long as we can get servicable replacement ( A la Tevez

) and that is why I am willing to wait a year before making judgement. But if Juve management's intention is to buy back other half of his contract then I will be very perplexed.
