The Stoke midfielder hasn’t been involved with the Tartan Army since playing the last 30 minutes of an end-of-season friendly against Qatar in June last year.
So he’s quite clearly well out of the picture with Strachan – the national team boss instead deciding to trust others, including John McGinn, who turns out in the Scottish Championship for Hibs.
It’s that selection which confuses Adam and he shared his frustrations while appearing on BBC 5 Live last night.
The Stoke midfielder has played nine times for his club this season and has enjoyed some strong form of late.
So he can’t understand why he’s been overlooked by Strachan, and also used other examples of poor treatment against Lee Wallace and Oliver Burke as evidence that it’s not right:
Has Charlie Adam summed up Gordon Strachan's Scotland selection policy perfectly here? Or is he holding a grudge? https://t.co/PtoriMsjHl

It’s strong stuff from Adam – which probably won’t go down well with Strachan and the rest of his Scotland staff.
The former Rangers man is 30 and has 26 international caps to his name, but he’s never really set the heather alight with his performances in a blue and white shirt.
So is he right to criticise Strachan? Or should he accept that his time as a Scotland player has been and gone?
