The Italy international returns to the capital club from Sassuolo, linking up once again with head coach Eusebio di Francesco
Roma have splashed out €10million to bring Lorenzo Pellegrini back to the Stadio Olimpico from Sassuolo.
Pellegrini emerged from Roma's academy before leaving for Sassuolo in 2015, where he has since scored 11 goals in 54 appearances across all competitions for the Serie A side, earning a maiden Italy call-up this season.
Having made his Azzurri bow against Liechtenstein in June, Pellegrini also helped Italy's Under-21s to the semi-finals of the European Championships, where they were beaten by Spain.
