England beat Rwanda 2-0 in their opening Group C match at the Under-17 World Cup in Mexico on Sunday.
Rwanda were under pressure from the start, but England failed to score until midway through the second half.
Hallam Hope of Everton broke the deadlock on 68 minutes and Liverpool's Raheem Sterling completed the win with four minutes remaining.
Rwanda's best chance came just before Hope's opener, when Bonfils Kabanda's shot cannoned off the England crossbar.
That was one of the few chances for Rwanda, who were playing their first match at any global football tournament.
England should have been in the lead earlier in the game but were denied by a combination of Marcel Nzarora in the Rwandan goal and their own poor finishing.
Rwanda's next match is on Wednesday against Uruguay, who top the table thanks to their 3-0 win over Canada.
