Everyone mentions Keita because he is talented, but he is such an idiot

He needs his attitude fixed if he is gonna come to us, and maybe more importantly, his workrate on the pitch. I can already imagine how much Allegri will be screaming at him if he comes. He contributes almost nothing defensively to Lazio, less than Pjaca, who Max always comments on in needing to improve.
Felipe Anderson is much more of a Juve player in terms of being complete and contributing to everything. Tactically he is years ahead of Keita.
I guess it depends on wanting left/center (Keita) or right/center (Anderson).
