Maybe Pogba has been a great player, but he has not played for quite a long time. and this was also expressed by Motta regarding himself before Juventus decided on the contract termination news. Motta's focus is on the present and he is concentrating on what he has and is still building at the moment.

Juventus are considering and if they come to a contract termination with Pogba, I see it's good decision for their club financially. With conditions of Pogba recent years, it's hard for him to return with good performances so continuing this contract, paying him high salary is not smart decision from Juventus.Source: Thiago Motta on Paul Pogba’s return

I believe Pogba will feel happy with this decision from Juventus too because he will be able to freely choose a club from Saudi Arabia, moving there to enjoy good salary and parties. He does not show that he is still ambitious with playing at highest level and winning big titles. With some Scudetto and World Cup title in 2018 tournament, Pogba satisfies with what he has had so far and money now is most important with him.
