Uruguay captain Diego Godin and Real Madrid midfielder Federico Valverde came close to breaking the deadlock when they hit the woodwork each half, while Hwang Ui-ju missed Korea’s best chance, parrying a shot from just 10 yards out for the goalkeeper to beat.

In particular, the South Americans kept Korean danger man Son calm.
Uruguay created the first clear chances as two crosses from centre-back Jose Maria Jimenez picked off runners coming in from a corner.
Valverde sliced the first over the bar, while Núñez failed to make proper contact in the second from just eight yards out with the goal at his mercy.
