Scott McKenna has seen a new rival for a place in the Scotland back line emerge in impressive fashion and he could not be happier.
"I couldn't have been any happier for Andy," McKenna said.
"Obviously I played probably nearly all my games for Aberdeen, more than 100 games, next to Andy, whether he was left-back or centre-back.
"And the help he gave me even since I was a kid coming though the academy at Aberdeen, he helped me so much. So I couldn't have been any happier for him and I couldn't wait to text him when I heard the news.
"Even when I was settling into the team, having that experience next to me, any time I made a mistake he was there to clear up for me. The bits of information he gave me on the pitch helped me massively.
"I have no doubt that Andy played a massive part in getting me to where I am just now.
"You will struggle to find a better professional than Andy. He is so regimented in everything he does. He doesn't change much at all and that's probably why at the age he is he never misses a training session, never misses any games.
"The two games he played last month for Scotland showed exactly why everyone was campaigning for him to get that call-up.
"It's just good both of us are here and both trying to push everyone in the squad for that place in the starting XI."
