Liverpool's couldn't contain his joy after scoring the decisive goal for Scotland in their nail-biting 2-1 victory over Poland, a moment made even more memorable as it marked his 80th cap.
The left-back, who has now equaled Darren Fletcher's appearance record , headed home in injury time to seal the win in the UEFA Nations League clash on Monday evening.
Reflecting on his journey with the national team, Robertson shared: "It's all about the team and all about the win, but this stadium holds a special place in my heart," where he first donned the Scottish jersey. "I made my debut here in a 1-0 win, which was the proudest moment of my career. I had all my family here.
"I didn't know how many caps I was going to get after that but to then come back here and now be top three and join an absolute legend in Darren Fletcher, who I was very fortunate enough to share a changing room with, it's great for me.
"I'm not a very emotional person but when you think about it - I just love playing for this country and to be able to get one cap, never mind 80, is such a special feeling.
"The goal was the cherry on top in the last minute, probably nobody expected that! I wish I scored more for my country because that feeling is like no other. Hopefully maybe there's a couple more to come."
Earlier, young sensation Ben Doak dazzled again, notching up his third assist in four games for Scotland, setting up John McGinn's opener and proving a constant threat until he was subbed off in the second half.
Scotland boss Steve Clarke commented: "I think he tired quite quickly in the second half. I should maybe have taken him off a little bit earlier.
"But he's a threat, he's very direct and he gets at defenders. Having been a full-back myself I know when you've got a winger like that who gets at you, it makes it difficult for the defenders, and he brings us something that little bit different."
