Born in Oliveira de Azeméis, Ferro started his football career at local club Oliveirense in 2005, where he remained until 2008. He then played for CD Estarreja and AD Taboeira before joining Benfica's youth system in 2011. Following his progress to the club's reserve team, he made his professional debut in a 2–1 away win over Oliveirense in LigaPro on 30 January 2016.
Ferro was promoted to Benfica's first team on 1 February 2019, alongside three other reserve team players, and six days later, he debuted with the Lisbon side as a 38th-minute substitute, replacing Jardel in a 2–1 home win over Sporting CP in the first leg of the Taça de Portugal semi-finals. In his first appearance as a starter, he scored his first goal for Benfica, the sixth in a 10–0 home thrashing of Nacional in Primeira Liga on 10 February. Four days later, he made his European debut as Benfica beat Galatasaray 2–1 in the first leg of the UEFA Europa League round of 32, their first ever victory in Turkey.
