Arguably, only Manchester United's fabled Class of '92 – featuring David Beckham, Ryan Giggs, Paul Scholes, Gary Neville, Nicky Butt, Keith Gillespie and substitute Robbie Savage – has boasted more firepower of the future in a single crop of under-18 players.

Conor Gallagher, widely regarded as one of the Premier League's brightest young talents, was only on the bench. They have already collected 44 England caps between them – with dozens more guaranteed to follow.
