John Mercado is an Ecuadorian attacker who plays for Sparta Prague. At 23, he is an interesting wide option for Ecuador because he offers speed, power, and the kind of direct running that can stretch a defence quickly.
John Anthony Mercado Cuero was born on 3 June 2002 in Guayaquil. He signed for Sparta Prague in August 2025 after two seasons with AVS in Portugal, and his move to the Czech champions put him into a stronger European setting at the same time that he was breaking into Ecuador's senior team.
Early Life and Background
Birthplace, family, and youth football journey
Mercado was born in Guayaquil and developed through the youth sides of Clan Juvenil and Panamá SC. That early route mattered because it helped shape him as a winger with pace and attacking freedom rather than as a rigid system player.
His youth football journey continued when he moved to Brazil to join Athletico Paranaense in 2020. That was a major step for a young Ecuadorian attacker because it took him away from home and placed him in a more demanding football environment at a key age.
By then, he had already represented Ecuador at youth level, including the 2019 FIFA U-17 World Cup. The combination of youth international football and Brazilian club development gave him a strong base before his senior career fully opened up.
Club Career
Early clubs and development
Mercado's senior debut came with Athletico Paranaense in 2022. He later spent time on loan with CSA in Brazil's second tier, which gave him needed minutes and helped his transition from youth football into professional competition.
In January 2023, he moved to Portugal with Vilafranquense. That transfer became more unusual after the club's reorganisation, with Mercado joining the newly formed AVS Futebol SAD. Instead of stalling his progress, the move gave him a platform to keep growing.
His first AVS season was a success. He helped the club win promotion to the Portuguese top flight, and his goal in the playoff against Portimonense was one of the key moments in that campaign.
Current club and recent form
Mercado followed that promotion by making an immediate impact in Liga Portugal, scoring on his top-flight debut. Sparta Prague then signed him in August 2025, seeing him as a dynamic winger who could add speed and strength to the attack.
Sparta's own introduction highlighted that he played 36 competitive matches in his final AVS season, with 4 goals and 4 assists. Two of those assists came in the playoff that helped AVS stay in the top division, which tells you that he contributed in important moments.
Current Sparta records list him as number 7 and describe him as a winger who can play on both sides, as a number ten, or even as a wing-back in the right system. That versatility is a big reason his profile stands out.
John Mercado - Stats and Performance
Mercado is best judged as a wide attacker who creates pressure through acceleration and movement. His game is not only about final numbers. He can unsettle full-backs, stretch a defensive line, and turn transitions into attacks very quickly.
| Season | Club | Appearances | Goals | Assists |
|---|---|---|---|---|
| 2024-25 | AVS | 36 | 4 | 4 |
| 2025-26 | Sparta Prague | 10 | 2 | 0 |
The bigger picture is that his production has come while adapting across different leagues. That makes his development more interesting than a simple raw total might suggest.
International Career
Caps, goals, and major tournaments
Mercado represented Ecuador at under-15, under-17, and under-20 level before receiving his first senior call-up in September 2024. He made his senior debut on 6 September 2024 in a World Cup qualifier against Brazil.
Current records place him on 5 senior caps and 0 goals. He also started against Peru in qualifying shortly after his debut, which showed that the national team were already willing to trust him in meaningful matches.
| National Team | Caps | Goals | Tournament Involvement |
|---|---|---|---|
| Ecuador | 5 | 0 | 2026 World Cup qualifying cycle |
For Ecuador in 2026, he is best viewed as a useful attacking option rather than a guaranteed starter. Even so, wingers with his pace and strength are always valuable in squad planning.
Playing Style and Key Strengths
Position, role, and standout qualities
Mercado mainly plays as a winger. Sparta describe him as a player with speed, strength, and excellent acceleration, and that fits what his recent career shows. He is a direct attacker who likes to drive at defenders rather than slowing the game down.
Another useful part of his profile is versatility. He can work on both wings, inside as a number ten, or in a wider wing-back role if the system asks for it. That flexibility can make him more valuable than a specialist who only fits one shape.
His key strengths are acceleration, movement, and his willingness to attack space early. If his end product becomes more consistent, he could become an even more serious option for Ecuador.
