Sérgio Miguel Relvas de Oliveira CvIH (born 2 June 1992) is a Portuguese professional footballer who plays as a central midfielder for Süper Lig club Galatasaray.
He spent the better part of his career with Porto after making his first-team debut at the age of 17, going on to appear in 174 competitive matches and win three Primeira Liga championships, three Taça de Portugal and two Supertaça Cândido de Oliveira. He was also loaned to Beira-Mar, Mechelen, Penafiel, Nantes, PAOK and Roma, winning another double with PAOK in the 2018–19 season and the Europa Conference League with Roma in 2022. In the Portuguese top division, he also represented Paços de Ferreira.
Oliveira finished second at the 2015 European Under-21 Championship with Portugal. He made his senior debut in 2018, being part of the squad at Euro 2020.
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.
Oliveira married Cristiana Gonçalves Pereira at Porto's Church of Our Lady of Lapa in June 2019. He thanked Julen Lopetegui for often leaving him on the Estádio do Dragão stands when the Spaniard was manager in 2015–16, as it was there that he met his wife.
