1000% this guy was bought as a mentor for Pogba. Since he came. There has been nothing coming from the Pogba camp other than reassurement of his continuing relationship with Juve.
Having this guy, a french-speaking veteran of the game. Who so happened to sort of botching his career when leaving Arsenal at the tender age of 18 for Real is maybe just what Pogba needed. 300 k euros isn't a lot to keep a potential world-beater happy at Juve.
