David Carmo

Porto On 5 July 2022, Carmo signed a five-year contract with Porto for €20 million plus €2.5 million in add-ons, which was the highest transfer fee paid between Portuguese clubs; the previous record was Rafa Silva's 2016 move from Braga to Benfica for €16.4 million. Owing to his sending-off for Braga, he missed the team's victory over Tondela in the Supertaça Cândido de Oliveira, as did a quartet of teammates given suspensions for insulting Benfica; he made his debut for the reserves on 7 August as the second-tier season began with a 1–0 home loss to Covilhã.

Carmo made his first-team debut on 3 September, winning all aerial duels in a 2–0 win at Gil Vicente. Four days later, on his maiden appearance in the UEFA Champions League, he played in a 2–1 group-stage loss at Atlético Madrid. After giving away a penalty in that competition against Club Brugge that manager Sérgio Conceição deemed unnecessary and childish, he was frequently kept out of the matchday squads; his 106-day exile ended on 12 February 2023, as a last-minute substitute in a 2–1 win at Sporting CP.

At the beginning of the 2023–24 season, Carmo played the full 90 minutes in a 1–0 away victory over Estrela da Amadora, earning praise from Conceição who, in the post-match press conference, named him and Pepe as the best players on the field. In December, however, he was relegated to Porto B reportedly due to "inappropriate behavior within the work group".

Olympiacos On 26 January 2024, Carmo joined Super League Greece club Olympiacos until the end of the campaign; according to reports, the deal involved a €600,000 loan fee and an optional buying clause of €18 million. He made nine complete appearances in their victorious run in the UEFA Conference League, including 120 minutes of the 1–0 victory against Fiorentina in the final.

Nottingham Forest Carmo agreed to a five-year deal at Premier League's Nottingham Forest on 25 August 2024. He was immediately loaned to Olympiacos until June 2025.

On 29 August 2025, Carmo was loaned to La Liga side Real Oviedo for one year.

Third Olympiacos spell Carmo returned to Olympiacos in June 2026, signing a three-year contract.

International career Portugal Carmo represented Portugal at under-19 and under-20 level. He started the 2018 UEFA European Under-19 Championship on the bench, but after Diogo Queirós was sent off against Italy in the group stage he never lost his place again, making four appearances for the champions in Finland. In October, he was named in a preliminary 55-man squad for the 2022 FIFA World Cup in Qatar.

Angola On 12 March 2024, Carmo was called up by the Angola national team. He made his debut ten days later in a friendly against Morocco, his 72nd-minute own goal being the only of the game in Agadir.

Carmo was included in the squad for the 2025 Africa Cup of Nations to be held in Morocco.

Style of play Carmo is predominantly left-footed, and his size is a significant factor in his defensive style and ability. He is a front-foot defender that engages in both ground and aerial duels, seeking to cut out danger at source by stepping in to intercept passes or muscle attackers off the ball. His physicality enables him to be a dominant presence, especially in the air.

Carmo also possesses quality in possession. His long-range distribution is one of the main features of his skillset, as he is adept at pinging switch passes to the opposite wing or driving a pass down the channel.
