Match after match, Kovacic is worse and worse. His level of confidence must be at 0% right now. Still, he's a whole different player for the NT and his huge talent is seen only there so far. But if Inter bought him for 15m and Juve are willing to pay about the same even after him flopping badly so far, then the Juve folk know that his performances have much more to do with the surrounding in Inter than with talent and potential.
