Ngumoha made history as Liverpool's youngest scorer when, aged 16, he scored the decisive goal in the 100th minute to beat Newcastle 3-2, but he managed just 10 senior starts throughout the last campaign. Slot and the Liverpool hierarchy would argue they were merely protecting him from the physical and psychological rigours of senior football during his first full season.
Questions remain over whether more minutes would have seen him fast-tracked into the World Cup squad. The London-born forward has clear ambitions to play at the highest level, and while the club maintains a protective stance, the player side appears eager for more frequent involvement. That could yet happen under new manager Andoni Iraola, but with European rivals sensing an opportunity, Liverpool face a battle to prove that Anfield remains the best place for his development.
