Mancini took over as national team captain in May 2018 after Italy fell to Sweden in a playoff and thus missed qualifying for the World Cup that year.
During his time as national team captain, the 58-year-old has had varying degrees of success. The country became European champions after winning on penalties against England in the 2021 European Championship final but missed out on qualification for the 2022 World Cup in Qatar.
Who will succeed Mancini will be announced within the next few days.
