Defeat to Republic of Ireland, and the manner, was a deep disappointment but Clarke did take the nation to a first major tournament this century just last summer.
Five years ago, the Scotland manager was just about to embark on his management career north of the border, taking over at Kilmarnock in October 2017. A lot has changed in that time not just for the manager – but for players in his squad too.
Some were in the bottom tier of Scottish football or in under-age groups. Some would go on to make big money and headline moves – and a few others have stayed where they are.
Here’s a look back on where the current Scotland squad have come from, and where they were five years ago – in 2017.
