**Newly promoted sides Marítimo and Académico de Viseu enter the 2026-27 Primeira Liga as the clearest relegation candidates due to limited top-flight experience and squad depth relative to the established bottom-half clubs.** Early season results show Marítimo competitive in the upper mid-table while Académico de Viseu sits near the lower positions, but historical patterns indicate promoted teams often struggle over the full 34-match campaign. Casa Pia, already heavy losers in opening fixtures including a 0-7 defeat, and Alverca appear vulnerable on current form and roster strength. With the bottom two sides facing automatic relegation to Liga Portugal 2 and 16th place entering a playoff against the third-placed side from the second division, trader consensus reflects these early indicators alongside typical factors such as home/away splits, fixture difficulty, and summer transfer activity. Outcomes remain fluid given the long season ahead.
