This is not just the case with the senior squad, but also the youth teams.
One Celtic player currently in the Scotland under-19s is Aidan Nesbitt. The attacking midfielder is currently out on loan with Partick Thistle and is in the Scotland youth team for upcoming games with Belgium, Croatia and Bulgaria.
He is in the Scotland under-19s team with Rangers players Ryan Hardie and Ross McCrorie. They too are currently out on loan, with Raith Rovers and Ayr United respectively.
Nesbitt believes that the Rangers pair will both benefit from their time out on loan just as he is. He told the Scottish FA earlier today:
“It’s been really good. I’ve started two games with Thistle in the Premiership so far, and I’ll sure I’ll get more opportunities this season if I keep working hard.
“It’s is a different experience from playing in the Development League. So far, in the matches I’ve played against St Johnstone and Motherwell, it’s been a real challenge, but a challenge I’ve really enjoyed. I’m sure it’s the exact same for Ryan and Ross at Raith and Ayr."
Hardie has played six times for Raith since joining the club and has scored four times. McCrorie, a defender, has featured six times for Ayr – even finding the net against Cowdenbeath at the start of the month.
Both will be hoping to one day go on and become regulars for Rangers at Ibrox – as will Nesbitt at Celtic Park.
For now the Old Firm trio will have to put domestic rivalry to one side in order to get results for the Scotland under-19s.
