Ex-Scotland centre-back Miller has been watching his beloved Dons closely this season and is of the belief that the form of 26-year old Reynolds has warranted a national team opportunity when Gordon Strachan's men take on Poland in a friendly in Warsaw on March 5.
"I'm not trying to tell Gordon his job, but there are a lot of important games coming up for Scotland and I'm sure he is looking at Mark Reynolds," Miller, capped 65 times, told the Scotsman.
"He's the right age, he's got that pace and he has experience now. He is playing for a good team with a lot of confidence.
"He's definitely a good central defender. His defensive play is of the highest order. He also has one thing that I never had, and that's pace. He doesn't have to think too much about the game, whereas I had to think my way through every game.
"His pace is electric. There's not many who go by him and at international level, I think that's very important. You've either got to be a great thinker or very fast in that position and I think he is putting himself forward for a Scotland place."
