Rio is an exciting left-winger who was signed in September 2024 after being on the books of Chelsea who were disappointed in losing him and have reportedly prohibited Liverpool's youth scouts to attend their academy games. Rio has been described as a generational talent and his self confidence was evident when he was asked in October 2024 that if it were a dream scenario, how would he like to be remembered in football: "I think for me, we're all believing that I can win the Ballon d'Or.” Rio answered, “I want to be regarded as one of the best players to ever play football and yeah, be a legend in the game." Rio's fee to be settled by a tribunal. The FA's rules state: 'In the event of a player, who is under the age of 24 prior to 30th June 2024, not accepting an offer of re-engagement and subsequently signing on contract or non-contract terms for a new club in England, the two clubs must agree a compensation fee. If the two clubs are unable to agree a compensation fee, the fee will be settled by a Tribunal and such decision will be final and binding.' The fee has not been settled yet but could likely be up to five million pounds.

He featured for both the U18s and U21s, displaying his versatility as a left-sided forward capable of playing across the front line. His performances in these matches highlighted his technical ability, flair, and understanding of the game, earning him recognition within the club's youth setup. Ngumoha's breakthrough came in January 2025 when he was handed his senior debut by manager Arne Slot in an FA Cup match against Accrington Stanley. At just 16 years old, he became the youngest Liverpool player to appear in the FA Cup, marking a historic moment in the club's rich history. The 2025 pre-season saw Ngumoha continue to impress with superb goals and assists. His performances during this period solidified his place in the first-team squad, with many observers noting his maturity and composure on the ball. On 25 August 2025, Ngumoha made his Premier League debut in a match against Newcastle United. Coming on as a substitute, he scored a dramatic last-minute winner, becoming Liverpool's youngest-ever goalscorer at 16 years and 361 days and the fourth youngest scorer in Premier League history. This goal not only secured a vital three points for Liverpool but also placed Ngumoha in the spotlight as one of the brightest young talents in English football.
