The 2009-10 campaign delivered a solid, mid-table finish for Paços de Ferreira as Capital do Móvel secured 10th place in the Primeira Liga. Following their run to the previous year's domestic cup finals, the season was defined by a European adventure that saw the team compete in the UEFA Europa League before being eliminated in the third qualifying round. Leading the line was William, whose 10 goals proved crucial for a side that secured their top-flight status. It was a year that cemented the club's continued presence on the European stage and remains a memorable chapter in the history of Os Castores.
