Real kicked off the 2017–18 campaign by winning its second consecutive and fourth overall UEFA Super Cup in a 2–1 victory against Manchester United. Five days later, Real Madrid beat Barcelona at the Camp Nou 3–1 in the first leg of the 2017 Supercopa de España and then defeated Barça 2–0 in the return leg, ending their 24 consecutive match scoring record in "El Clásico" matches and winning the second trophy of the season. On 16 December 2017, Real beat Brazilian club Grêmio 1–0 in the FIFA Club World Cup final and became the first team to retain the trophy. In the 2017–18 UEFA Champions League, Madrid once again progressed to the final where they defeated Liverpool 3–1 to become the first club to win three straight titles in the Champions League era, as well as the first team to win three consecutive titles in the European Cup/Champions League since Bayern Munich in 1976. The trophy also marked Madrid's fourth win in five years and their eighth consecutive semi-final appearance. On 31 May, only five days after winning the final, Zidane announced his resignation as Real Madrid manager, citing the club's "need for change" as his rationale for departing.
