This move is very good for him immediately, and good for Juve down the road. The pressure is on to win and win now. I can understand why Conte would be hesitant to use a 19 year old on the back line in this, the most important season in the last 3 years. Juve make money now off of him, and if he pans out, then great. Juve pay a little more than what they sold his half for, but you have a far more experienced CB coming back into the fold. He was not going to get any playing time in meaningful matches this season. It just wasn't going to happen
