He joined Benfica in 1938, winning one league and a cup in five years there. He then moved to Estoril Praia, staying there for 14 years.
Born in Alhos Vedros, Elói started at Barreirense, before moving to Benfica in 1938, making his debut at the hands of Janos Biri on 8 October 1939, against Belenenses. He went on to appear in every game that Benfica played in that season, making 35 appearances, many of those alongside Gaspar Pinto, helping the club win the 1939–40 Taça de Portugal.
His partnership with Gaspar Pinto was kept in 1940–41, but without the same success, as Benfica did not win anything. Still, he played every game possible, making 31 appearances. In 1941–42 he battled for a first team place with Ricardo Freire, appearing in 6 league games, as Benfica won the league. Elói left the club in 1942 after playing in 75 games, subsequently starting a long career at Estoril Praia.
