Sérgio Oliveira

Oliveira was selected by the Portugal under-19 team for the 2010 UEFA European Championship; in the tournament in France, he scored in a 2–0 group stage victory over Italy as both nations went on to be eliminated after the first three games. He was also part of the under-20 side at the 2011 FIFA World Cup in Colombia, finishing in second place. Oliveira was the captain of the under-21s at the 2015 European Championship in the Czech Republic. He hit the crossbar in the first half of the final against Sweden, and was replaced as they went on to lose in a penalty shootout after a 0–0 draw in Prague. Oliveira was selected by full side manager Fernando Santos to a preliminary 35-man squad for the 2018 FIFA World Cup, but he did not make the final cut. He won his first cap on 6 September of that year, replacing William Carvalho for the final ten minutes of a 1–1 friendly draw with Croatia in São João da Venda, Algarve. His maiden competitive appearance took place four days later, when he came on for the same player late into a 1–0 win over Italy for the UEFA Nations League. On 20 May 2021, Oliveira was named in the squad for UEFA Euro 2020. He made his debut in the competition on 23 June, in a 2–2 draw against France which closed the group stage. In October 2022, Oliveira was included in a preliminary 55-man squad for the 2022 World Cup in Qatar.

Porto

Born in Paços de Brandão, Santa Maria da Feira, Aveiro District, Oliveira arrived at Porto's youth system in 2002, at the age of 10. On 17 October 2009, he became the club's youngest ever player to appear for the first team, at the age of 17 years, four months and 15 days, in a 4–0 home win against Sertanense in the third round of the Taça de Portugal; during the game, he provided an assist for Hulk in one of the goals. He signed a renewed contract the following month, running until June 2012 with a €30 million buyout clause. Oliveira was loaned to Beira-Mar of the Primeira Liga for the 2010–11 campaign. He debuted in the competition on 23 October 2010, playing one minute in a 1–1 away draw with Paços de Ferreira. In the summer of 2011, still owned by Porto, Oliveira was deemed surplus to requirements by new manager Vítor Pereira as practically all Portuguese players, and joined Belgian Pro League club Mechelen. He scored his first career goals on 21 September in the sixth round of the national cup away to Oostende, two in a 3–0 victory; his one goal of the league season was a consolation in a 3–2 loss at Standard Liège on 25 November.
