They have never won a major trophy, but returned to Portugal’s top flight in 2017 after winning the LigaPro – Portugal’s second tier.
Portimonense topped the table ahead of Aves by just two points, with a further gap of 17 points to the third-place side.
The club reached their peak in the 1980s as they played the entire decade in the top flight, reached the Cup of Portugal semi-finals in 1983, 1987 and 1988, while also competing in the UEFA Cup in 1985–86.
Portimonense beat Serbia’s Partizan Belgrade 1-0 at home in the first leg of their first-round tie, but eventually lost 4-1 on aggregate.
In the 1990’s and 2000’s the club primarily played in the Segunda Liga, while also having a brief spell in the third tier.
On their most recent return to the top flight during the 2017/18 season, Portimonense finished 10th in the 18-team Primeira Liga.
This season in the top-flight, Portimonense had Colombian forward Jackson Martinez on loan from China’s Guangzhou Evergrande among their ranks.
