Porto aims to maintain their perfect start to the Primeira Liga season as they face Moreirense at Estadio do Dragao in the opening match of matchday five on Friday evening. The Dragons have secured victories in all four of their league matches thus far, placing them two points ahead at the top of the Portuguese league table. In contrast, Moreirense currently occupies the 11th spot, having gathered four points from three matches. Last weekend, Porto displayed confidence on both offense and defense, defeating newly promoted Academico de Viseu 3-0 with three first-half goals scored by Andre Silva, Gabri Veiga, and William Gomes. This win marked Porto's first instance of scoring more than two goals in a match this season and maintained their status as one of only two teams yet to concede a goal. They had previously won against Alverca (2-0), Rio Ave (2-0), and Arouca (2-0) in the league. Francesco Farioli's squad has now gone six competitive matches without conceding, a streak that began with their narrow Super Cup win over Torreense on August 1 and continued with a 1-0 victory against Santa Clara at the end of last season. Porto appears to have successfully implemented the defensive strategy that led them to achieve a league-high 21 clean sheets in the 2025-26 season, and they may well surpass that number this year, as they had already conceded a goal by this point last season. Last year, it took until matchday four for Porto to allow their first league goal, while they need three more wins to equal the winning streak that kicked off their 2025-26 Primeira Liga campaign. Supporters of the Dragons can feel optimistic about approaching that record this weekend, as Porto has triumphed in their last eight league encounters against Moreirense, including a 3-0 win in their last meeting at the Dragao in March.
