This bodes very well. Raiola saying he'd gladly sell him is expected because he wants a huge fee. However, I think Pogba really likes Juve, particularly because of how close the team seems off the pitch. Remember when Vidal was angry about being subbed a few weeks back? Pogba goes up to him and says "we're a family". That statement in itself is a testament to how the player feels about Juve. Raiola's comments are a huge change from his words from a month ago. It's very possible Pogba told him to shut up because he wants to stay.
Plus if he left Juve, who would he have to compete with in practice in that ball lobbing competition. I cant imagine mourinho doing it.
