Fabio Vieira scored an early goal for FC Porto as it beat Olympiakos Piraeus 2-0 in their Champions League Group C clash at the Estadio do Dragao on Tuesday.
The win was a first in the pool for Porto and moved it into second place after two rounds of matches, three points behind leader Manchester City, who has a full haul of six following its 3-0 victory at Olympique Marseille.
The open contest swung in the home side's favor when it went ahead on 11 minutes after Olympiakos captain Andreas Bouchalakis misplaced a pass and Porto was able to swarm into the box, with 20-year-old Vieira providing the finishing touch for his first Champions League goal.
Olympiakos had its moments -- winger Lazar Randjelovic forced a good save from Agustin Marchesin, before wasting a golden chance when he shot tamely at the keeper with the goal at his mercy.
Sergio Oliveira made the points safe with a second goal for Porto five minutes from time as he converted Moussa Marega's cross.
The Greek side next faces home and away games against Manchester City next month that could go a long way to determining its knockout-stage chances.
