During the summer 2019, Lovren demanded a transfer since he did not want to be a substitute. The strongest interest was expressed by Serie A clubs Milan and Roma. He was therefore left out of the squad for 2019 UEFA Super Cup, which Liverpool won beating Chelsea on penalties. Lovren returned to the squad for an EFL Cup match against MK Dons on 25 September. He went on to solidify his spot in the starting XI following Joël Matip's injury. On 27 November, he scored the equalizer in the Champions League group stage match against Napoli, that ended as a 1–1 draw. However, on 10 December, he suffered a knee injury in a game against Red Bull Salzburg and was substituted for Joe Gomez. The injury forced him to miss the 2019 FIFA Club World Cup, which Liverpool won beating Flamengo 1–0 in the final. He returned on 26 January 2020 and captained the team in an FA Cup game against Shrewsbury Town that ended as a 2–2 draw. On 25 June, after Chelsea had defeated Manchester City 2–1, Liverpool mathematically won the Premier League, making Lovren the first Croatian in history to achieve that.
