Former Flying Eagles invitee Jonathan Spiff signs his first senior deal with Argentine giants River Plate until December 2028.

Jonathan Spiff, a 19-year-old forward born in Buenos Aires, has officially signed his first senior professional contract with River Plate, securing his future at the Argentine club until December 2028.

The talented youngster, who holds dual eligibility for Nigeria and Argentina through his Nigerian father, caught widespread attention earlier when he received an invite to join the Flying Eagles during preparations for the 2025 FIFA U-20 World Cup.

After rising through the club youth ranks and making his Reserve debut in February 2026, Spiff earned a promotion to the senior squad, according to information published by sports247.

Journey Through River Plate Youth Academy

Spiff journey with River Plate began when he was just seven years old after he successfully impressed coaches during a club trial. He spent his formative years steadily moving through the various youth categories in Buenos Aires.

His consistent development eventually culminated in a Reserve team debut in February 2026. Impressive goalscoring form in the youth setup convinced the coaching staff to hand the teenager a golden opportunity with the senior team.

Senior Debut and Copa Sudamericana Experience

In May, the young forward reached a major career milestone when he was named in the River Plate matchday squad for a Copa Sudamericana fixture against Bragantino.

He came off the bench late in that 1-1 draw to make his official first-team debut. He also featured against Blooming in the same continental competition before returning temporarily to continue his development in the Reserve squad.

International Eligibility and Future Outlook

While his club future is now firmly secured in Argentina until 2028, Spiff remains internationally eligible to represent Nigeria at the senior level because of his paternal roots.

The recent contract extension represents a significant reward for his dedication, marking a vital step forward as he looks to build upon his early first-team minutes in South American professional football.
