Chelsea defender Malang Sarr has joined Ligue 1 club Monaco on a season-long loan, which includes an option to buy.
The French defender, 23, moved to Chelsea on a five-year deal in August 2020 after reaching the end of his contract at French side Nice.
Sarr made 21 appearances for the Premier League club last season after spending the 2020-21 campaign at Porto.
Monaco finished third in France's top-flight last term and reached the last-16 of the Europa League.
"I am very happy to join Monaco and to be back in Ligue 1, a league in which I started and which I know well," Sarr said.
