The 2017-18 campaign was a season of dramatic dichotomy for Benfica, as the four-time defending champions finished a competitive 2nd in the Primeira Liga, ultimately ending their long title reign after being pipped by rivals Porto. Leading the charge was the sensational Brazilian Jonas, who clinched the league's Golden Boot with a phenomenal 34 goals in just 30 matches, his best-ever scoring season. Despite securing the Supertaça Cândido de Oliveira, the season was also defined by a historically turbulent UEFA Champions League run, where Os Encarnados failed to earn a single point in the group stage. It remains a memorable year for the brilliance of Jonas, even as the club endured significant managerial and financial turbulence that signaled the end of an era.
