Why don't we loan him with an option to sell as long as Pogba is included in any deal next summer. We could also have a buy back option at a set price if we are to take him back if he does become the next Maldini. We hold the cards if Juve want him, although if he is homesick and wants to move back to Italy which isn't as far from his homeland as the UK then we should also consider this. A lot of former Yugoslav's play out their careers in Italy and maybe this would suit Nastasic better than keeping him here if his heart isn't in it.
