Scotland's hopes of progressing from Group C hang in the balance.
Scotland's attacking questions and defensive resilience leave Group C hopes finely poised.
They have three points from a 1-0 win over Haiti and a 1-0 defeat by Morocco.

That tally of points could yet prove enough if they avoid a heavy loss to Brazil on Wednesday, while a draw would leave them on the brink of reaching the last 32.
But what have the two matches in Boston revealed before the Tartan Army descends on Miami?
In the build-up to the tournament, head coach Steve Clarke switched to a 4-4-2 formation for friendlies against Curacao and Bolivia with encouraging results.
Against modest opposition, Scotland scored eight goals across those two games and arrived at the World Cup in confident mood.
Clarke persisted with the same shape for the opening match against Haiti, but Scotland managed fewer shots than their opponents and posted a lower expected goals figure (1.05 compared with 1.21).
John McGinn's winner arrived via a deflection, while starting forwards Lawrence Shankland and Che Adams had little influence.
Shankland dropped to the bench against Morocco as Clarke reinforced his midfield, but Adams again struggled to impose himself.
Frequently isolated up front, the striker was unable to hold the ball up or help Scotland gain territory. He managed just 11 touches before being replaced by Lyndon Dykes after 71 minutes, with Scotland ending the game without a shot on target.
Clarke is expected to retain the same system against Brazil, though personnel changes are possible. Dykes, Shankland, Ross Stewart and George Hirst are all vying with Adams to lead the attack.
Winger Ben Doak, who impressed against Haiti, injected much-needed energy after coming off the bench as Scotland finished strongly against Morocco.
Fellow wide player Findlay Curtis, 19, made his World Cup debut as a substitute against Haiti and also offers pace and trickery. He could have a role to play in midweek as Scotland seek to ease the pressure.
Defensive solidity
Although Scotland have struggled to create clear chances in their two group matches, they have largely remained solid at the back.
One mistake against Morocco was ruthlessly punished as Ismael Saibari burst beyond Grant Hanley to score the only goal after just 70 seconds.
From that point onwards, however, Scotland's back four restricted their highly rated opponents to relatively few clear openings.
Jack Hendry was outstanding, snuffing out danger on more than one occasion with his pace and anticipation. His block to deny Saibari a second was of the highest quality.
That resilience could prove crucial in Scotland's final group game, where another disciplined defensive display will be essential.
No Scotland, no party...
The Scotland fans impressed all the world in the tournament so far. Hopefully, this upcoming match won't be the last time they show up.
