Alexander-Arnold began the 2019–20 campaign with his position as Liverpool's right-back cemented, and provided the assist for Origi's goal in the club's 4–1 opening game win over Norwich City. In doing so, he became only the eighth player in the Premier League era to register an assist in five consecutive games, and the first to do so for Liverpool. He appeared in subsequent wins over Southampton and Arsenal, as well as in Liverpool's triumph over Chelsea in the UEFA Super Cup where he scored a penalty in the shoot-out. He then scored his first goal of the season during Liverpool's 2–1 league win over the Blues from a set-piece routine that was later nominated for the Premier League Goal of the Month award. The following month, he was nominated for the 2019 Ballon d'Or award, alongside six of his Liverpool teammates.
