I'll just leave here some potential Portuguese teams for your save then.
- Boavista FC: Last team to win the league besides the "big 3" Porto, Benfica and Sporting. They are currently in a bad place financially and had a transfer embargo but I'm not sure when it's lifted.
- Belenenses: The only other Portuguese team to win the league besides the big 3 but they have an interesting story. In simple terms their board had a disagreement between members and the club was divided in two: CF Belenenses and Belenenses SAD. Belenenses SAD is seen like the black sheep in this situation since they kept pretty much everything whilst CF Belenenses had to start from the beginning in the 3rd division. There's two main goals for this save: the first is to overtake Belenenses SAD and the ultimate goal is to make them champions again.
- Académica de Coimbra, Beira-mar, Olhanense: All teams that used to be in the top flight but have been struggling lately.
