Bosnian captain Dzeko will succeed Emir Spahic as his country's most capped player should he feature against Austria in the UEFA Nations League on Wednesday (AEST).

The 32-year-old has scored 52 international goals in his 94 appearances to date and his goals-to-game ratio is marginally better than Ronaldo's for Portugal and Messi's for Argentina.

Dzeko also became the first man to score at least 50 goals in three of Europe's top five leagues earlier this year, having done so with Wolfsburg, Manchester City and Roma, yet he does not tend to garner the same acclaim that other leading strikers across the continent get.

However, Juventus midfielder Pjanic, who played with Dzeko at Roma, insists the striker commands plenty of respect at home.

"I don't think he's underrated - he's done great things recently," Pjanic said.

"For the national team he's the guy who's scored the most goals. We know that he's important.

"He does important things for his club. I think he's a great player, so he's not underrated."
