Pogba Going to Stay After All?

So today, when United took on West Brom, and won 2-0 to a brace from Rooney, the supposedly youngster who was said to go to Juventus (Paul Pogba), made an appearance. He played magnificently, and almost scored his first goal for the club. Plus his partnership with Cleverly looks VERY promising. If Fergie let Pogba play today, there obviously must be something there, and they may have come to an agreement.
What do you guys think? Will he stay? Is it a good thing if he does?
