With the departure of former captain Andrés Iniesta in May 2018, Messi was named the team's new captain for the following season. On 12 August, he lifted his first title as Barcelona's captain, the Supercopa de España, following a 2–1 victory over Sevilla. On 19 August, Messi scored twice in helping Barcelona defeat Alavés 3–0 in their first La Liga match of the season, with his first goal, a free kick that he rolled under the jumping Alavés wall, making history in being Barcelona's 6000th goal in La Liga. On 18 September, Messi scored a hat-trick in a 4–0 home win over PSV Eindhoven in Barcelona's opening Champions League group stage match of the season, setting a new record for most hat-tricks in the competition, with eight. On 20 October, Messi scored in a 4–2 home win over Sevilla, but was later forced off in the 26th minute after falling awkwardly and injuring his right arm; tests later confirmed that he had fractured his radial bone, ruling him out for approximately three weeks. On 8 December, Messi scored two free kicks – his ninth and tenth goals from set pieces during the calendar year – in a 4–0 away win over "Derbi barceloní" rivals Espanyol in La Liga; this was the first time ever that he had managed such a feat in the league. His first goal was also his 10th league goal of the season, making him the first player ever to reach double figures in La Liga for 13 consecutive seasons.
