Nacional 0-4 Benfica; Porto 3-0 Moreirense; Rio Ave 2-1 Portimonense; Aves 0-1 Maritimo
Benfica continued their unbeaten start to the season by thumping Nacional 4-0 away, while Porto stayed within touching distance of the top three by cruising to a victory of their own. In the other games of the day, Rio Ave continued to pile on the misery for Portimonense, who remain rooted to the bottom of the table after their 2-1 home defeat, while Aves also suffered yet another loss, to high-flying Maritimo.
Benfica's first goal came just before the half hour mark, after a delightful outside-of-the-foot through ball from Salvio played in Seferovic, who just beat the offside trap to score his first goal of the season, coolly slotting home into the bottom left corner.
The roles were reversed for the second goal, scored on the stroke of half time, where 19-year old Gedson Fernandes capitalised on some sloppy Nacional passing, intercepting the play before giving the ball to the in-form Pizzi, who played it out wide to Seferovic. The Swiss striker's whipped cross then met the rising head of Salvio, who beat the goalkeeper with a directed downward header.
Benfica continued to dominate and, with just 15 minutes of the game remaining, Pizzi's nonchalant, pinged, inch-perfect ball fell to the feet of the overlapping Grimaldo, who, after a smooth first touch, buried the ball into the bottom right corner.
And Benfica wrapped up the convincing win with a goal in the 93rd minute, Pizzi again involved in the goal, playing a delightful defence-splitting ball through to Benfica's pacey winger Rafa, who delicately lifted the ball over the onrushing goalkeeper. A glorious goal to finish off a glorious performance for the Eagles.
Meanwhile, Porto made little work of getting the job done over Moreirense, earning a much-needed victory to keep within touching distance of Benfica and top spot.
Their first goal came after just a quarter of an hour was played, after Telles' corner was nodded on to Hector Herrera at the back post,who took the ball down and thumped it past the helpless Moreirense goalkeeper. They then doubled their lead thanks to Aboubakar, who reacted very quickly after Marega's light, placed shot came off the inside of the post, firing in on the rebound from close range.
The score remained 2-0 heading into half time, a game Porto were dominating and looking likely to go on and win in convincing fashion. However, having already let a two goal lead slip twice in a row leading into this match - most notably last week, where they went from 2-0 up at half time to 3-2 down by the full time whistle at home against Guimaraes - Porto were not going to allow complacency to set in.
And they finished off the game in the dying minutes, with Marega getting on the end of Otavio's low cross, thumping the ball into the back of the net.
There was also a notable debutant for Porto in the match, with 20-year old Eder Militao playing in the heart of defence alongside compatriot Felipe for the full 90 minutes, and all eyes were on the highly rated youngster to see how he coped with the occasion. To very few people's surprise, Militao slotted into the side seamlessly, putting in a great display in his first appearance in a Porto shirt, and it was discovered after the conclusion of the game that he had even earned a call-up to the Brazil national team for his recent form, most notably at his former cub Sao Paulo, an exceptional achievement for a 20-year old, serving as testament to how highly regarded he is back in his home country.
Elsewhere on the day, Rio Ave earned a 2-1 victory over Portimonense - who recently completed the signing of former Porto star Jackson Martinez - capitalising on Portimonense's poor discipline, who received two second-half red cards to be reduced to nine men, allowing Rio Ave to score in the closing minutes of the game thanks to Gelson Dala.
Like Portimonense, Aves' poor start to the season also continued, with Maritimo getting their third victory from four games, with centreback Zainadine Junior getting the only goal of the match.
