The Liverpool pair were introduced from the bench in the latter stages of the Group A tie in Jeonju, South Korea, with goals from Dominic Calvert-Lewin and Adam Armstrong either side of half-time having given their side an advantage.
Dominic Solanke added a stoppage-time penalty for England, who thereby took early command of their section ahead of meetings with Guinea (May 23) and the host nation (May 26).
