Casa Pia produced one of the surprises of the early Liga Portugal season by taking a shock lead against league leaders Porto, but the Dragons responded with a ruthless second-half display to secure a commanding 4-1 victory at the Estadio Municipal de Rio Maior and maintain their perfect start to the campaign. The hosts stunned the visitors on 43 minutes when Henrique Araujo converted a penalty, awarded after Pablo Rosario was adjudged to have fouled Selvi Clua inside the area. It was a moment that briefly threatened to derail Porto's impressive run, but the visitors equalised in first-half stoppage time when Andre Silva pounced on a loose ball following a corner, stabbing home from close range to level the scores at the break. In the second half, the Dragons took complete control and never looked back. Jakub Kiwior rose highest to head home Gabri Veiga's pinpoint corner on 60 minutes, giving Porto the lead for the first time. Just six minutes later, Borja Sainz capitalised on a defensive error to make it 3-1, effectively putting the game beyond Casa Pia's reach. Santiago Gimenez sealed the rout from the penalty spot on 90+1, scoring his first goal for the club and ending a near year-long drought in domestic competition. Porto dominated possession with 60% and registered 15 shots on the night. Gabri Veiga was named man of the match for his two assists, which proved decisive in turning the game around. With 18 points from six games, Porto remain top of the table, while Casa Pia stay bottom with just one point from their opening fixtures. Next up for Porto is a huge clash with rivals Benfica, a match that could define the early title race in Portugal.
