Diogo Goncalves

Born in Almodôvar, Gonçalves started his career at local club CD Almodôvar in 2005. Two years later, he joined FC Ferreiras, before moving to S.L. Benfica's youth system in 2008.

After being promoted from the youth team, Gonçalves debuted for the reserve team, Benfica B, as a substitute, playing 20 minutes in a Segunda Liga 4–1 home win over Oliveirense on 14 February 2015. On 24 May, he scored his first goal for Benfica B in a 2–1 home win over Vitória de Guimarães B. Five days later, he scored the only goal of a friendly held for the opening of F.C. United of Manchester's Broadhurst Park.

On 9 August 2017, Gonçalves debuted for Benfica's senior team in a 3–1 victory over Braga in the Primeira Liga. Later on, he made his UEFA Champions League debut in a 1–0 home loss to Manchester United on 18 October.

On 14 June 2018, Gonçalves joined EFL Championship club Nottingham Forest on loan for the 2018–19 season with the option of making the transfer permanent at the end of the season. He made his only EFL Championship start in the opening day 1–1 draw at Bristol City and was subsequently used sparingly by managers Aitor Karanka and Martin O'Neill, totalling ten games in all.

Gonçalves and Benfica teammate Gonçalo Rodrigues both moved on 26 June 2019 to Famalicão, who were returning to the Primeira Liga after a quarter-century away; his deal was again a season-long loan. He scored his first goal on 19 December in a 3–0 home win over Mafra to reach the quarter-finals of the Taça de Portugal; there on 15 January 2020 he netted the only goal at Paços de Ferreira to put the team from Vila Nova de Famalicão into the last four for the first time since 1946.
