Early results in the 2026-27 Primeira Liga have highlighted vulnerabilities among the promoted sides and established lower-table clubs. Academico de Viseu, newly promoted, remains winless after four matches and faces immediate adaptation challenges against established defenses, while Casa Pia sits bottom with zero points and a heavy goal deficit. Simulations from models like estimador.pt assign Casa Pia the highest relegation probability, followed by Academico Viseu, Rio Ave, and Moreirense, reflecting concerns over squad depth, recent form, and fixture difficulty. Porto’s defensive solidity and the top clubs’ consistency further widen the gap for survival candidates, though managerial changes and summer transfers could yet reshape mid-season momentum in the 18-team division.
