It looks pretty sure that he will extend his contract in next days, and won't be sold/loaned in summer.
This according to Romeo Agresti, a source very close to the board, usually his rumours are true. Conte is said to trust him, despite the few playing time he's been given this season, but with the 3 defence sees him as a vice-Bonucci. I'd like to see him play as a CM, last year as a CM was great, doing things like:
Dat assist for Giaccherini (pure quality)
And goal vs Atalanta in scudetto party. Great goal.
But Conte is stucked on him as a DC. I don't see him that great as a DC, maybe he just needs experience. We'll see.
