Saleh Gomaa created the opening goal in Nacional's 1-1 Liga Sagres draw at Olhanense.
The 20-year-old Gomaa, on loan to the Portuguese side from ENPPI, whipped in a pinpoint cross for Venzuelan striker Mario Rondon to head the opener before the league strugglers pegged them back two minutes later.
The Egypt international played the full 90 minutes after also featuring for the whole game in the 4-2 loss to league leaders Benfica last week.
Gomaa, who has made nine appearances for Nacional so far this season, has one goal to his name after scoring in the 2-0 win over Belenenses last month.
Another Egyptian to play a full match was centre half Ali Ghazal. He was cautioned in the game for his third match in a row.
Nacional are currently fifth in the league and host giants Porto at the weekend.
