The 27-year-old Everton forward, who will win a silver medal from the Scottish Football Association if he plays against Croatia on Tuesday, has scored just twice to date, with his decisive goal against Lithuania in September 2011 coming on the last occasion Scotland won a competitive qualifier at home.
Naismith knows he must do better. "I don't think I will look too far ahead and expect to get 50 but when I made my debut, in the Faroe Islands under Alex McLeish, I did have a feeling that I would like to get to 25 as it is a small milestone. "If I play on Tuesday night it will be a special moment for me and one that will drive me on to hopefully get to 50."
Successes have been few and far between for Naismith, but there are some fond memories.
"Probably the most memorable game was my home debut against Holland," he said. "They beat us 1-0 but that is the one that stands out, from the moment we came out of the tunnel and the atmosphere. We performed well for probably about 80 minutes but unfortunately it was a mistake that cost us a draw. Scoring for my country is great and also doing it against the world champions [Spain] was a highlight as well."
He accepts that his goals tally should probably be higher. .
"That's one criticism of myself," he said. "Although I play a bit deeper and wider I have always been in positions to get chances and scoring twice out of 24 is not as good a ratio as I would like. So there have been some good times but I would like there to be more good times than bad in the next 25, if I get there."
