The hosts, who have three points to their name, are currently sitting in the Primeira Liga relegation zone, while Vizela are a point better off in 14th place.
Match preview
After giving up a lead on three occasions to lose 4-3 in their league opener, Estoril responded positively to record a 2-0 win over Arouca in their first home game of the Primeira Liga season.
However, they have been unable to add to their tally since that result, losing three straight matches against Estrela, Boavista and Gil Vicente.
Despite scoring three goals in their away meeting with Gil Vicente last weekend, Estoril's vulnerable backline proved to be their downfall, shipping five goals inside the first hour to ensure they returned home empty-handed.
Estoril have now lost four of their opening five league games and conceded 13 goals across those defeats, highlighting a key area for improvement if they are to experience an upturn in fortunes.
While they are struggling defensively, Estoril have had no such problems at the other end of the pitch, having found the net in all five of their top-flight matches.
Vizela experienced an eventful start to the Primeira Liga season, falling to a narrow 3-2 defeat to Sporting Lisbon, before playing out an entertaining draw 2-2 draw against Arouca.
After losing out to Vitoria Guimaraes on matchday three, Vizela edged out Gil Vicente on home turf to finally clinch their first league win of Pablo Villar's tenure.
Unfortunately for Vizela, their maiden victory was followed by their first home league defeat of the campaign after suffering a narrow 2-1 loss to reigning champions Benfica in their most recent fixture.
They will now turn their attention to Saturday's away trip, and they will be looking to end a run of five consecutive away defeats in the top flight.
While that poor run of form may be a cause for concern, Vizela have won their last two away matches against Estoril after winning 2-1 in April 2022 and cruising to a 3-0 victory when the two sides went head-to-head in March.
