FC Porto won their local derby against Boavista at the Dragão Stadium while Braga came from behind to beat Vitória Setúbal.
The most impressive performance came from Sporting, whose 4-2 victory over Estoril did not reflect the home team’s superiority.
Benfica manager Rui Vitória dropped keeper Julius Caesar in favour of Ederson Moraes, who made his first start of the season, for the visit to GD Chaves.
The first-half was played at a slow pace with both sides having goals ruled out for offside. Chaves had two great opportunities to take the lead but on both occasions Rafael Lopes fluffed his chances. The Eagles had to wait until the 69th minute to unlock the Chaves defence when Kostas Mitroglou headed Grimaldo’s free-kick past keeper Antonio Filipe.
A quarter-of-an-hour later another Grimaldo free-kick ricocheted off the Chaves defensive wall but this time fell to Pizzi, outside the penalty area, who curled his shot into the top corner to sew up the points.
Jorge Jesus sprang a surprise by giving Jefferson a rare start at left-back. João Pereira, Bryan Ruiz and Bas Dost were also recalled as Sporting attempted to bounce back from two straight defeats.
Skipper Adrien and William Carvalho were dominant in midfield; Gelson Martins and Bryan Ruiz caused all sorts of problems for the Estoril defence and the only surprise was that the hosts had just a single goal to show for their first-half superiority. In the thirteenth minute Bryan Ruiz played a perfectly weighted pass to Gelson, whose pinpoint cross was guided into the net by the diving head of Bas Dost.
Fifteen minutes after the interval Coates took advantage of a misjudgement by Estoril goalkeeper Moreira to head in a corner. Soon afterwards it was 3-0 as a lovely through ball from the outstanding William Carvalho was slotted home by Bas Dost.
As well as his four goals in as many games, the Dutch striker’s clever link-up play and good work rate suggests the record fee of over €10m paid to Wolfsburg was money well spent. A late flurry of goals saw Bruno Gomes score a brace for Estoril, with Brazilian striker André grabbing his first goal for Sporting in between.
FC Porto were a goal down, at home to city neighbours Boavista, after just four minutes when Henrique headed home Espinho’s free-kick. Porto were on level terms fifteen minutes later when André Silva outjumped a static Boavista defence.
The home side took the lead from the penalty spot just before the interval after Otávio was tripped and André Silva calmly stroked home his second goal of the game.
Telles added a third, five minutes from the end, when Boavista keeper Kamran committed a howler as he let a left-wing cross slip through his hands. Braga came from behind to beat Vitória Setúbal 2-1 at the Quarry, thanks to the evergreen Alan, the 37-year-old Brazilian scoring one and setting up the other goal for Wilson Eduardo.
The Eagles, Lions and Dragons may be heading up the domestic league in Portugal but it was two Portuguese players who secured victory for the Wolves in the English Championship.
João Teixeira, on loan from Benfica, scored his first two goals for Wolverhampton Wanderers as they beat Brentford 3-1 at Molineux.
Portugal international and former Benfica youth product Ivan Cavaleiro, a record €7m summer signing from Monaco, scored a stoppage-time third for the midlands team.
