João Mário

Porto

Born in São João da Madeira, Aveiro District, João Mário began at hometown club Sanjoanense before joining the ranks of Porto at the age of 9. On 7 October 2018, while still a junior, he made his professional debut with the reserve team in a LigaPro match against Arouca, coming on for Tiago Matos for the last 11 minutes of a 1–0 home loss. The following 5 January, he scored his first goal in a 2–2 draw with Benfica B also at the Estádio Dr. Jorge Sampaio.

On 10 June 2020, João Mário had his first call-up to Porto's first team, remaining unused as they won 1–0 at home to Marítimo. He debuted on 15 July as they won the Primeira Liga title with a 2–0 win over Sporting CP also at the Estádio do Dragão, playing the last five minutes in place of Luis Díaz. On 1 August, he was on the bench in the 2–1 defeat of Benfica in the final of the Taça de Portugal, securing a double.

João Mário was eventually reconverted by manager Sérgio Conceição into a right-back. He was later occasionally deployed again as winger, but struggled to provide assists from that position; he totalled 26 during his spell.
