Roma have sacked Jose Mourinho with immediate effect, with the club lying in ninth place in Serie A, according to the Daily Mail.
Mourinho joined Roma in May 2021 and spent two-and-a-half years in the role, leading them to the Europa Conference League title in 2022.
He also guided them to the Europa League final last season, before they were defeated by Sevilla on penalties.
In a statement, Roma said: 'We would like to thank José on behalf of all of us at AS Roma for his passion and efforts since his arrival at the club.
'We will always have great memories of his tenure at Roma, but we believe that an immediate change is in the best interests of the club."
Lazio are five points off Serie A's final Champions League qualifying spot and last week were knocked out of the Coppa Italia by city rivals Lazio.
His final game in charge was Sunday's 3-1 defeat to AC Milan - which a suspended Mourinho had to watch from the stands - meaning the Stadio Olympico-based outfit had won just one of their past six league games.
Mourinho's contract was set to expire at the end of this season and there had been increasing speculation surrounding his future before Roma's announcement on Tuesday.
