The 21-year-old missed out on a place in Gordon Strachan's senior squad for the games against Czech Republic and Denmark.
Scotland coach Stuart McCall has challenged Rangers winger Barrie McKay to prove a point to Gordon Strachan by making his mark during the under-21s' upcoming games with France and Northern Ireland, the Evening Times reports.
The 21-year-old was left out of Strachan's senior squad for their games against Czech Republic and Denmark - despite the former Celtic boss' decision to name almost two completely different teams for the two games meaning that 33 players were called up - but McCall has suggested that Hibernian star John McGinn's path into the first-team should motivate McKay to use the games in Ricky Sbragia's squad to send a message to Strachan.
"Barrie is obviously in the under-21s. Gordon went out to watch the u21s over four or five days the last time and I know John McGinn caught his eye in the training sessions, you get to see the character," he told the Evening Times.
"When was the squad was named McGinn was also prominent in the Edinburgh derbies. It’s a different position, though.
"Again, McKay is different because we have so many wide players and it would probably be better for the manager to have him be in the u21s and stand out there. When you play there you have to make your mark.
"I think during the last u21 game Barrie had a little bit of tonsillitis and he didn't make a mark on it. But when you get the opportunity, especially at the home games, you need to impress."
With McGinn also being the only Scotland-based player in the squad to play their football outside the Scottish Premiership, McKay will also know that his chances of forcing his way into Strachan's plans will be helped enormously once Mark Warburton's side are back in the top flight.
While they suffered a surprising defeat to Falkirk in their most recent game - which saw the Bairns come from 2-0 down to win - the loss appears to be simply delaying the inevitable as the Gers boast an 11 point lead at the top of the table with just seven games to go.
And if McKay can be as impressive in the top tier as he has been this season, then there can surely be no arguments against his inclusion in one of the future senior squads.
