Clarke surprised many by deploying a rigid 4-4-2 shape in Copenhagen. The approach was a success, keeping a clean sheet and claiming a point.
The head coach then went for a 4-2-3-1 formation in Hungary against Belarus, with John McGinn, Scott McTominay and Ben Gannon-Doak playing behind striker Che Adams.
It was not a vintage performance from the Scots, but they got the job done in a deserved 2-0 victory.
The main notable change in Clarke’s squad this month has been a recall for veteran goalkeeper Craig Gordon.
The Hearts man has yet to play a minute of club football this season, but that is the same story for Nottingham Forest’s Angus Gunn, who started both qualifiers in September.
Would you consider bringing Gordon back in? And what about the other 10 positions and formation?
