On 29 April 2019, Ranocchia's contract with Inter was extended to 2021. Moreover, he reunited with his first coach in senior professional football, Antonio Conte, who was appointed manager of Inter ahead of the 2019–20 season. Although he was initially used as a starter for the first two games of the season, even earning praise in the media over his performances, he was once again relegated to the bench as the season progressed. However, he was given an opportunity to start on 20 February 2020, during which he made his 200th Inter appearance in all competitions by captaining the team in a 2–0 win at Ludogorets Razgrad in the first leg of the round of 32 of the Europa League.
