Sérgio Antônio Soler de Oliveira Júnior

Born in Monte Aprazível, São Paulo, Serginho joined Santos FC's youth setup in 2011, aged 15, after being released by rivals São Paulo FC due to a recurrent back injury. He soon earned plaudits for his performances with the under-20's, being a key midfield unit during the 2014 Copa São Paulo de Futebol Júnior winning campaign. On 9 March 2014 Serginho made his first-team debut, coming on as a late substitute in a 4–1 home success over Oeste for the Campeonato Paulista championship. He made his Série A debut on 11 September, again from the bench in a 1–3 away loss against Sport Recife. On 15 January 2016, Serginho renewed his contract – which was due to expire at the end of the year – until 2018. On 7 July, he was loaned to fellow top tier club Vitória until the end of the year. Serginho scored his first professional goal 17 November 2016, netting Vitória's second in a 2–3 away loss against former club Santos. The following 17 February he moved to Santo André, on loan until the end of the 2017 Campeonato Paulista. Upon returning, Serginho did not play a single minute until July 2017, in a 1–0 away win against Atlético Mineiro. He started to feature more regularly in late September, mainly used as a substitute. On 23 January 2018, Serginho was loaned to fellow top tier club América Mineiro for one year. On 15 April, he scored a brace in a 3–0 home defeat of Sport. On 29 July 2018, he moved to J1 League club Kashima Antlers. Serginho made an impressive appearance with Kashima…

Although Serginho was born in Brazil, he did not represent the nation internationally at any level. On 13 March 2025, Serginho became a naturalised citizen of China. He was subsequently called up by China national team in preparation for two of their 2026 FIFA World Cup qualifier matches against Saudi Arabia and Australia. He debuted for China on 25 March 2025 in a 0–2 lost to Australia in the 2026 FIFA World Cup qualifier. He came on as a substitute at half-time. Serginho was called up to the China's squad for the 2025 EAFF E-1 Football Championship where he featured in all of the matches.
