Jose Mourinho will take over as coach of Roma on a three-year deal from next season, the Serie A club announced on Tuesday.
Mourinho, sacked by Premier League club Tottenham last month, will replace fellow Portuguese Paulo Fonseca who will leave Roma at the end of the current campaign.
Mourinho returns to Italy where he led Inter Milan to the treble in 2010.
The 58-year-old also won the Champions League with Porto in 2004, three Premier League titles with Chelsea and La Liga with Real Madrid in 2012.
Mourinho, who led Manchester United to the Europa League in 2017, has signed a contract with Roma that runs until June 30, 2024.
Mourinho has claimed 25 major trophies in his career to date and joins a club that hasn’t won Serie A since 2001.
Earlier Roma confirmed that Fonseca would leave the club after two years with the three-time Italian champions who are trophyless since 2008.
Fonseca, 48, joined the club in 2019 on a two-year contract with the option for a third year if the club reached the Champions League next season.
The club finished fifth in Serie A last campaign and are currently seventh, nine points behind city rivals Lazio who sit sixth and have a game in hand.
Roma trail Mourinho’s former club Manchester United 6-2 going into Thursday’s second leg of their Europa League semi-final in the Italian capital.
Fonseca replaced Claudio Ranieri, who had a brief spell as coach after Eusebio Di Francesco was sacked in January 2019.
Di Francesco had guided the club to the Champions League semi-finals in 2018.
