ATLANTA, United States (AFP) — Lamine Yamal's return sparked Spain's World Cup into life as the European champions ran riot to beat Saudi Arabia 4-0 in Atlanta. Making his first start in two months after a hamstring injury, Yamal ended La Roja's long wait for a World Cup goal just 10 minutes in. Mikel Oyarzabal then struck twice to put Luis de la Fuente's men 3-0 up inside 24 minutes.
