His career was all but associated with Sporting, for which he appeared in 423 competitive games.
Born in Barreiro, Setúbal District, Azevedo started playing football with two local teams, F.C. Barreirense and Luso Futebol Clube. He signed with Sporting Clube de Portugal in 1935, going on to remain with the club for the following 18 seasons and win 13 major titles, including nine Primeira Liga championships.
On 17 November 1946, in a game against S.L. Benfica for the Lisbon Championship, Azevedo broke an arm, had to leave the field but returned during the second half with the score at 1–1 to help secure a 3–1 win. He retired in 1954 at 39, after a season with neighbouring Clube Oriental de Lisboa.
Azevedo earned 19 caps for the Portugal national team in one full decade, making his debut on 28 November 1937 in a 1–2 friendly loss to Spain. His only competitive appearance took place on 1 May 1938, where a 0–1 defeat against Switzerland in Italy meant failure to qualify for that year's FIFA World Cup.
Azevedo returned to Portugal in 1982, dying in his hometown on 4 January 1991 at the age of 75.
