Sassuolo are moving for Barcelona defender Marlon Santos.
Mundo Deportivo says Sassuolo have launched a €12m offer for the Brazilian youngster.
Marlon has welcomed the approach, though favours a move to England and wants to wait until Thursday's Premier League transfer deadline before making any decision.
West Ham remain keen on the defender, who spent last season on-loan with Nice.
Marlon also has two rival offers from the LaLiga and another from Borussia Monchengladbach in front of him.
