Scotland’s World Cup qualification campaign has been one of the shortest in memory at just 74 days, but could end up being one of the most glorious in a generation if they are able to secure maximum points against Greece and Denmark next month.
With a golden opportunity to qualify for their first World Cup since 1998 on the horizon, Clarke is expected to name his Scotland squad for the qualifying fixtures at Hampden Park on Monday, and several players will be sweating on their inclusion for the crunch double header.
Already on 10 points from their opening four games and second behind group leaders Denmark only on goal difference, the October internationals against Greece and Belarus saw his side pick up maximum points and secure a place in at least the World Cup playoffs.
However, with another two wins, Scotland could go one better and seal automatic qualification for next summer’s tournament in the USA, Mexico, and Canada - an opportunity they want to grasp with both hands. Sadly for the Scotland boss, he does have some injury concerns ahead of the game, while others may return to the squad ahead of others who are out of form.
But how will his squad for the potentially history-defining World Cup qualifiers look? And whose squad place is in doubt?
Ahead of the games with Greece and Denmark in November, we look at the 11 players who could miss out on Scotland call-ups.

6. George Hirst - Ipswich Town
Had started just one of Ipswich Town's last five games, and hasn't scored for over a month prior to the weekend. With several other strikers in better form, and hoping for a return to the squad, Clarke may have to omit him for the World Cup qualifying clashes in November - his two goals for Ipswich on Saturday may have rescued him, though. | Getty Images Photo: Getty Images
7. Connor Barron - Rangers
Drafted into the squad following injuries for the game against Belarus, the Rangers midfielder put in an impressive performance in his side's 1-0 win over Hibs in midweek. He's not a regular for his club side, though, and could be one of those who miss out on the squad when it's announced on Monday. | SNS Group Photo: SNS Group
8. Josh Mulligan - Hibs
A late addition to the Scotland squad last month, the uncapped Hibs midfielder offers versatility, but could be one of the unlucky ones to miss out of the squad next month. | SNS Group Photo: SNS Group
