The world top and richest clubs will be after Pogba. Bayern, Chelsea, City, Madrid, PSG...
They'll offer him a fortune in terms of salaries and a concrete opportunity to win CL in his first year.
This kid is ambitious... it's up to him now. If he wants to leave, he'll leave. And Raiola isn't the best of influences in this case.
Juve should sell only if Pogba rejects any renewal and states that he wants to go. Then we'll have no other option.
