Does a clinical first-half showing in a blistering opening period against Bolivia in New Jersey mean there will be little change for a seismic Haiti encounter?
Captain Andy Robertson and Aaron Hickey seem to be certainties in the full-back positions, while winger Ben Gannon-Doak, midfielder Scott McTominay – tummy trouble permitting – and striker Shankland are all expected to start.
Shankland worked well with Adams on Saturday and the hope from many of the Tartan Army will be that they are paired together again.
Former Scotland striker Kenny Miller says he would be “very surprised” if the duo do not spearhead a 4-4-2.
“Clarke has played that formation for these two preparation games,” he said. “It makes sense and he’s looked at a couple of different combinations within that.
“The performance on Saturday with Shankland and Adams – and the fact they were both on the scoresheet – means I would be very surprised if it wasn’t those two.”
In the midfield four behind them, Christie and Ferguson will likely be battling it out for the final spot if Aston Villa captain John McGinn comes back into the XI.
It is assumed goalkeeper Angus Gunn will be first pick after playing the full 90 minutes against Bolivia, but there is uncertainty about the centre-backs.
Scott McKenna, John Souttar, Grant Hanley and Jack Hendry all received minutes in the past two friendlies, so Clarke has a decision or two to make in his backline.
