The Academy graduates both started and played the full 90 minutes as England beat Venezuela 1-0 in Suwon, South Korea. Everton's Dominic Calvert-Lewin struck the winner in the 35th minute. Newcastle goalkeeper Freddie Woodman saved a penalty in the second half.
It was the first time England have played in a world final and won on the global stage since famously lifting the World Cup back in 1966.
Josh came back into the team after suspension and was outstanding in central midfield, rattling the underside of the crossbar with a fine strike in the second half. Kyle also impressed in his left-back role.
