Having claimed a sixth league and cup double in the 2008–09 season, Porto was on course to emulate the "Penta" of the late 1990s, but the series was broken by Benfica in the following season. Although Ferreira won his first Supertaça and defended the Taça de Portugal title, the team's failure to claim a fifth consecutive league – finishing third, outside the Champions League-qualifying places – and a 3–0 defeat against Benfica in the final of the Taça da Liga contributed to his resignation at the end of the season. A home win against Benfica prevented the rivals from celebrating the league title at the Estádio do Dragão. Under Ferreira's steering, Porto always qualified for the Champions League knockout stage, reaching the quarter-finals in 2008–09, where it was eliminated by holders Manchester United.
