Anticipation is building for England's last-16 clash against Mexico, scheduled to get underway at 1am.
The contest has been threatened by delays due to a weather warning in Mexico City for thunderstorms and lightning.
Kick-off time had initially been moved to 7pm, but was U-turned back to the original 1am start after backlash from both football associations.
Pubs will stay open until 5am in England and Wales for the match, after outgoing Prime Minister Sir Keir Starmer passed emergency legislation.
A win for the Three Lions will see them face either Brazil or Norway in the quarter-finals of the World Cup.
England captain Harry Kane said he hopes his side can provide the perfect antidote for Monday morning blues by reaching the World Cup quarter-finals.
He said: "Obviously it's good news that the pubs are staying open for the fans.
"We know how much the World Cup means to everyone and all the fans at home, so I'm hoping there will be a few all-nighters to be honest, just going all the way through and celebrating until the next day and then catch up on some sleep after that.
"I think everyone would love nothing more than to be celebrating as the sun's rising at 5 or 6am."
How did we get here?

Harry Kane is 95 per cent the reason England are in the last-16, but they still needed to make it through the group.
The Three Lions kicked off their World Cup campaign on June 17 against Croatia with a 4-2 victory.
Heading into half-time at 2-2 after Kane scored twice, a couple of goals from Jude Bellingham and Marcus Rashford got England off to the perfect start.
Game two saw Thomas Tuchel's side play Ghana, in an uninspiring 0-0, which has quickly been erased from the memory bank by several England supporters.
Panama in game three proved better, with a 2-0 win thanks to second-half goals from Bellingham and Kane.
Seven points out of nine saw England finish top of their group, setting up a tie against DR Congo, who frustrated fans, going 1-0 up inside seven minutes.
With 15 minutes to play, up stepped Captain Kane, with a sensational brace to set-up tonight's contest against Mexico.

Fresh injury doubt for Thomas Tuchel

There is a fresh injury doubt for Thomas Tuchel, as Djed Spence is unlikely to start.
It is understood the right-back is nursing an injury which will impact his involvement in the game, according to Sky.
The full-back position has been a headache for the England boss, already having Reece James out of action and Jarell Quansah returning from injury.
The Three Lions will need to get it right with Mexico's main threat going forward, Julian Quinones, set to start on the left wing.
