If Juventus is looking to win the champions league, why make such a deal with Real madrid? They would basically be strengthening them with Pogba and taking what Madrid already considered needless (James and Morata) from their hands. If Pogba really wants to go, the best option would be to sell to United who aren't at least an immediate threat and use the money to pursue other targets to create a team that would potentially be capable of winning the CL. I see no point in aiding a rival team, especially for that type of deal.
Also, Real Madrid won the champions league last year without Pogba.
