He honored his contract, and didn't agitate for a move, so that was class on his part, compared to the exits arranged by Couties, Sterling, Tom Ince, et al.
Was he going to get playing time this season with Keita and Fabinho coming in? I doubt that.
He's getting sub appearances only at Juve.
He just moved on, and we've replaced him or upgraded on his position. No hard feelings on either side.
