Three Leeds United players will have their World Cup fate determined this evening when group B's final round of fixtures conclude.
Brenden Aaronson and Tyler Adams will be in action for the USA facing off against Iran while Wales' Dan James, who is currently on loan at Fulham, will face off against England.
After convincingly beating Iran 6-2 in their opening group stage game, England sit top of group B heading into the final set of fixtures.
Iran sit second having beaten James and Wales last time out 2-0, with the USA third and Wales bottom of group B.
While Wales drew their opener with the USA 1-1, their loss to Iran dealt a hammer blow to their knockout stage hopes.
Conversely, a win for the USA over Iran, who drew their first two games, would definitely see Aaronson and Adams through.
With that in mind, LeedsLive took a look at all the group B permutations heading into the final set of games...
Group B Permutations
England beat Wales, Iran beat USA/England draw with Wales and USA draw with Iran
Should both England and Iran, who currently sit first and second in group B, beat Wales and the USA respectively, they will both qualify.
If England and Iran draw their final group games, they will still both qualify first and second.
England beat Wales, Iran draws with USA
Again, if England win and Iran draw, both sides will go through ahead of Wales and the USA.
England beat Wales, USA beat Iran
If England and the USA win, they would both go through. The USA would leapfrog Iran into second place on five points.
England draw with Wales, USA beat Iran
Should England only be able to muster up a draw against Wales and the USA beat Iran, the winner of group B will be decided by goal difference.
England currently have a +4 goal difference compared to the USA's 0, meaning they would need to beat Iran convincingly to claim top spot.
Wales beat England, USA beat Iran
Should Wales beat England and the USA beat Iran, Adams, Aaronson and co will advance as group B winners. Second place would be decided on goal difference.
England's +4 goal difference is superior to Wales' -2, meaning Rob Page's side would need to hammer the Three Lions convincingly in order to qualify.
Wales beat England, Iran beat USA
Should Iran beat the USA, and Wales beat England, then Iran will go through as group B winners on six points.
England would finish up on four points, the same as Wales, which would result in a goal difference tiebreaker.
Wales beat England, Iran draw with USA
If Wales beat England and Iran draw with the USA, England would still likely go through as group winners on goal difference.
A draw between Iran and the USA would leave Iran on four points but with a goal difference of -2.
Wales could therefore go through in second if they beat England 3-0.
