The World Cup rolls on into its 11th day with European champions Spain set to take on Saudi Arabia.
Group H remains all square with all four sides on one point following Spain's goalless draw with Cape Verde and Saudi Arabia's 1-1 stalemate against Uruguay.
That means that unlike in some of the other groups, nothing can be definitively decided in this encounter - but either nation could take a big step towards qualification for the final 32 with a victory.

The referee for Spain vs Saudi Arabia
Kick-off is set for midday local time (5pm UK time) at the Mercedes-Benz Stadium in Atlanta, Georgia.
FIFA have confirmed the eight officials who will take charge of the game, with Raphael Claus the main in the middle of it all.
The 46-year-old Brazilian has been on the FIFA list since 2015 and is held as one of South America's top officials.
Claus refereed the 2024 Copa America final between Argentina and Colombia in 2024, and is a regular presence in the Copa Libertadores, where he once oversaw a semi-final between River Plate and Boca Juniors. Fiesty.
This will be Claus' first game of this World Cup, but he did referee two games in the group stage of the 2022 edition: England's 6-2 win over Iran - which featured a contentious late penalty for Iran - and Morocco's 2-1 win over Canada.
Assisting Claus are not elves or reindeer, but simply two Brazilian linesmen in the shape of Danilo Manis and Rafael Alves.
Colombia's Andres Rojas will be in the dugout as the fourth official, and his countryman Alexander Guzman is the reserve official.
VAR duties will be led by another Colombian, Nicolas Gallo.
Erick Miranda is the assistant VAR, while Guillermo Pacheco is the support VAR. Both hail from Mexico.
What's the difference between assistant and support? The assistant helps makes decisions, the support coordinates communication and keeps an eye on the live feed while checks are ongoing. Dazzle your mates down the pub with that.
