João Mendes

Porto On 7 July 2021, Mendes joined FC Porto on a three-year contract, being assigned to the B team in the Liga Portugal 2. He made his debut as a professional on 7 August, featuring 90 minutes of a 2–2 home draw against C.D. Trofense.

Mendes' first competitive appearance for the main squad took place on 15 December 2021, as an 80th-minute substitute for Nanu in the 1–0 home win over Rio Ave F.C. in the group stage of the Taça da Liga as his team was already eliminated. A month later, he made his Primeira Liga bow by replacing Wendell late into a 4–1 away victory against B-SAD.

On 23 October 2022, Mendes scored his first second-tier goal for Porto's reserves, in a 3–0 win at Trofense. His second arrived the following 29 January, in the 2–1 away defeat of S.C. Covilhã.

Vitória Guimarães Mendes returned to Vitória on 15 June 2024, signing a four-year deal. On 10 January 2026, in the League Cup final against S.C. Braga, he was sent off for two yellow cards; the second resulted in an injury-time penalty, but Charles Silva saved Rodrigo Zalazar's shot and Mendes' team won 2–1 for their first-ever title in the competition.
