Scotland Under-21 manager Scott Gemmill believes there is "real optimism" that several of his players can make the step up to Steve Clarke's senior squad in the near future.
Winger Findlay Curtis, currently on loan to Kilmarnock from Rangers, is the latest to make the jump to the full international set-up, but Gemmill says others are pushing hard for recognition, including in-form Falkirk striker Barney Stewart.
Gemmill believes the gap between youth and senior international football is closing.
"I think there definitely is real optimism if you look at how many of the under-21 players are moving forward to the men's A team," he said.
"Historically, that has happened, but the gap between the levels seems to be shortening.
"In the past, you might have had to wait for an opportunity – now it can happen with a phone call. Steve has shown he's ready to give young players that opportunity."
Stewart's rise has been particularly notable. Just 18 months ago, he was playing for Edinburgh University while studying sports science but is now Falkirk's top scorer in the Scottish Premiership.
"It's an indication of how well his club have done to identify and recruit him – and how well he has taken that opportunity," Gemmill added.
"You can talk about potential, but you never really know until players are given the chance. To perform consistently at that level, he deserves a lot of credit.
"It's about continuous improvement – and he's shown that, along with the right mentality and attitude."
Gemmill's side sit third in their in their Euro 2027 qualifying group, level on poins with Friday's visitors to Tannadice, the Czech Republic, before travelling to face group leaders Portugal next Tuesday.
