Club career
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.[2] 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.[3] He made his Série A debut on 11 September, again from the bench in a 1–3 away loss against Sport Recife.[4]
On 15 January 2016, Serginho renewed his contract – which was due to expire at the end of the year – until 2018.[5] On 7 July, he was loaned to fellow top tier club Vitória until the end of the year.[6]
Serginho scored his first professional goal 17 November 2016, netting Vitória's second in a 2–3 away loss against former club Santos.[7] The following 17 February he moved to Santo André, on loan until the end of the 2017 Campeonato Paulista.[8]
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.[9]
On 23 January 2018, Serginho was loaned to fellow top tier club América Mineiro for one year.[10] 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.[11] Serginho made an impressive appearance with Kashima in the 2018 AFC Champions League.[12][13]
On 27 January 2025, Changchun Yatai announced that Serginho was released after the end of his contract.[14]
Beijing Guoan
On 2 February 2025, fellow Chinese Super League side Beijing Guoan announced that Serginho has completed the transfer to the club. Serginho chose to wear the number 7 shirt.[15] He debuted on 29 March 2025 in a 1–1 draw against Chengdu Rongcheng for the club in matchday 3 of Chinese Super League.[16]
His first goal for the club, a header from a corner, came on 15 April 2025 in a 4–4 league draw against Wuhan Three Towns.[17]
International career
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.[18][19] 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.[20]
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.
