Blues loan striker Dane Scarlett won his fourth England Elite League cap as the 10-man Young Lions came from behind twice to beat Germany 3-2 via a stoppage-time winner at the Jahnstadion in Regensburg.
Scarlett, 19, who is on loan with the Blues for the season from Tottenham, came on as a 61st-minute sub and hit the inside of the post soon afterwards.
England were reduced to 10 men when Reading’s Nelson Abbey was red-carded on 79, however, a minute into injury time Chelsea’s Charlie Webster netted a dramatic winning goal.
Mateo Joseph, Leeds, and Southampton's Sam Edozie had netted the Young Lions' earlier goals.
The victory is the squad previously billed as the U20s’ first of the competition following three defeats and the loss the Germans’ first. Germany remain top of the eight-team group and England seventh.
