The Tartan Army face hosts Germany at Munich’s Allianz Arena in Friday night’s curtain-raiser, with kick-off set for 20:00 BST.
McTominay played an integral role in helping Steve Clarke’s men seal a place at a second straight Euros, scoring seven goals in qualification as Scotland finished runners-up behind Spain in Group A.
Now he’s feeling ready and recharged ahead of a huge night in his career.
“I feel refreshed. I’ve had a good break, a short one after the FA Cup final and I’m raring to go,” he told Scotland’s official YouTube channel.
