Will Porto keep pace with current league-leaders Benfica?
Last Friday night, Sérgio Conceição’s team enjoyed a statement victory, hammering neighbours Braga 4-1.
Evanilson, Stephen Eustáquio, Pepê and Galeno all on target.
This means the champions remain three points behind Benfica; those two meet in O Clássico on 21 October.
Since that victory, Porto’s Champions League campaign has also got up and running, beating Bayer Leverkusen 2-0 on Tuesday.
Zaidu Sanusi and Galeno the scorers at Estádio do Dragão, while Diogo Costa was also a hero, saving a first half penalty when the game was still goalless.
Despite losing their first two matches in that group, Dragões are now firmly back in the hunt for a top two finish.
Here, Portimonense will be hoping Porto’s focus is elsewhere, as they look to continue their excellent start to the campaign.
Paulo Sérgio’s side sit fifth, despite actually losing 1-0 to Vizela last weekend.
Nevertheless, having won their last three at Estádio Municipal de Portimão, they’ll be hopeful of springing a surprise.
