Qualification for the quarter-finals, being played on Saturday evening, is guaranteed and a point from their final game against Algeria would ensure top spot.
The football tournament is restricted to those under the age of twenty-three but teams are allowed three over age players, one of whom is former Olhanense favourite Salvador Agra now with Madeira side Nacional.
Two English Premier League players are also featured, Liverpool defender Tiago Ilori and Manchester United second choice keeper Joel Castro Pereira.
Tiago Ilori was born in Hampstead, London to a British father of Nigerian descent and a Portuguese mother. Ilori then spent his childhood in Albufeira where he started playing football with local Imortal DC.
Could the Portugal Olympic team emulate the national team? With hosts Brazil struggling to qualify they certainly have a chance.
