The Saints star was named in the squad to face the Faroes Islands back in November and he's now being tipped for a crack at Brazil's Samba superstars in London next month.
Davidson intends to keep his feet firmly planted on the ground.
He told the Scottish Sun: "It's great to hear your name being mentioned about Scotland.
"I've been unfortunate in the sense that I've had to withdraw from a few squads because of injury. I was involved against the Faroes and although I didn't play it was great to be in and around the boys.
"It certainly gives you a taste for it but my focus is on St Johnstone. We're going well at the moment, but we have a lot of important games coming up.
"I can't afford to think about anything else. Hopefully, if I keep playing well, then Scotland will take care of itself.
"I'm not getting my hopes up and I'm not setting myself any targets.
"It would be great to be involved again but right now I just have to concentrate on St Johnstone."
