AC Milan s Manuel Locatelli has completed a loan move to Sassuolo, who have an obligation to purchase the midfielder.
Locatelli burst on to the scene as a teenager with a wondergoal in a 1-0 Serie A defeat of Juventus in October 2016.
But the 20-year-old started only five league games in the 2017-18 season and has been allowed to leave by coach Gennaro Gattuso.
