Roma Born in
Rome, Pellegrini, who had suffered from
arrhythmia as a youngster, joined the youth academy of local side
Roma at the age of nine. Having previously represented the club in the
UEFA Youth League, he was handed his senior debut at the age of 18 by
manager Rudi Garcia on 22 March 2015, coming on as a second-half
substitute for
Salih Uçan in a 1–0
Serie A victory against
Cesena.
Sassuolo On 30 June 2015, Pellegrini
signed for fellow Serie A side
Sassuolo for a fee of €1.25 million. In terms of the transfer agreement, Roma retained a buy-back-clause which afforded the club the opportunity to re-purchase Pellegrini at a future stage. Pellegrini made his debut for the club on 8 November 2015, starting in a 1–0 league victory against
Carpi, and scored his first goal the following month when he netted in a 3–0 victory against
Sampdoria. He eventually made 20 appearances for the season, including one in the
Coppa Italia, and scored three goals. During the
2016–17 season, Pellegrini became the youngest player to have a hand in ten goals in one Serie A campaign, having registered six goals and four assists by 10 April 2017. He made 34 appearances across all competitions for the campaign, scoring eight goals registering seven assists, before re-signing for Roma at the end of the season.
Return to Roma in 2017. On 30 June 2017, Roma exercised the buyback clause of €10 million, which was included in Pellegrini's
transfer agreement with Sassuolo, to bring him back to Rome on a five-year deal. On the same day Roma youth product
Federico Ricci joined Sassuolo outright, Pellegrini scored his first-ever goal for the club on 1 December 2017, netting Roma's third goal in a 3–1 league victory against
SPAL. On 25 May 2022, Pellegrini captained A.S. Roma in the inaugural
Europa Conference League final, which his team won 1–0 against
Feyenoord. He was also named Player of the Season in that competition. ==International career==
