A horror own-goal from England's Fikayo Tomori rescued a point for Guinea in their 2017 FIFA Under-20 World Cup Group A fixture in Jeonju on Tuesday, but the African side may feel they deserved more from the encounter.
Lewis Cook gave England the lead seven minutes into the second half, but shortly afterwards a moment of madness from Tomori brought Guinea level.
Both sides had excellent chances to win the game but had to settle for a point, the first of the competition for Guinea, who lost their opener 3-0 to South Korea on Saturday.
Their final pool match will be on Friday against Argentina, which will be a must-win if they are to make the second round. England are likely already there having defeated Argentina in their opener, with the top two teams in each pool advancing, as well as the four best third-place finishers.
Everton winger Ademola Lookman was lively for the English and had the first real opening when he wriggled past three defenders, but placed his shot wide.
The best chance of the opening half fell to Guinea teenager Oumar Toure from Juventus, who saw the ball sit perfectly for a shot from 10-yards, but blasted over when he had to hit the target.
Newcastle United forward Adam Armstrong also put the ball well over with time and space in the box as the finishing from both sides in the opening period left a lot to be desired.
Cook grabbed the opener with a 35-yard low shot that skidded off the wet surface and defeated Guinea goalkeeper Sekouba Camara, who had the elements to contend with, but will feel he should have done much better.
That lead lasted just six minutes though as pressure on Chelsea cenre-back Tomori forced him to boot the ball 45-yards back to goalkeeper Dean Henderson, who had come well off his line and was beaten by the power in the delivery.
It was comical from England, with Tomori committing the cardinal sin of passing back to the keeper in line with his goals, rather than wide of either post.
England might have won it at the death when Everton teammates Dominic Calvert-Lewin and JonJoe Kenny combined, but the latter put his shot into the side-netting with just Camara to beat.
