Robbie Neilson aims to use Nathaniel Atkinson's Australia call-up as a carrot for future transfers.
The full-back only signed for Hearts in January, then an under-23 international, but has now graduated to the full squad.
The Gorgie side's boss wants his team to be full of international class players.
But he also thinks it can help him persuade targets that a move to Tynecastle can do the same for their prospects.
“I think that's really important,” he said.
“Hearts should be a team with international players as the majority of the starting line-up, whether that's for Scotland or different nations.
“Nathaniel’s call-up is great from that point of view, but also for attracting players. We can show them the pathway that we've managed to create for a couple of boys.
“We spoke to Nathaniel when we were trying to sign him about coming here, playing for Hearts, raising his profile and trying to get into the national team. He has managed to do that. I still think there's a lot of development within him as a player.
“The call-up gives you belief about the level you can play at. Nat's a confident boy anyway so I'm sure going away will help him, playing with good players and against good players. It will improve him and it's a great one for him.”
