With the news of the move today for Kevin-Prince Boateng to Barcelona, Sassuolo are active looking for his replacement. There are two options that Sassuolo are looking at. First is Sampdoria's Gianluca Caprari. Caprari is not currently available, though the winger is the first choice for De Zerbi.
The other name is Balotelli, who has not completed the final details with a move to Marseille (there have been steps taken but currently no completed deal). Balotelli has been offered to Sassuolo, and they are considering whether to make an offer.
