"It is a great boost for me personally and obviously I am very happy to be in the squad," said a delighted Berra.
"I think I have kept up a consistent level of performance since coming into the Hearts side and the only way you can get into the international squad is by doing well at club level.
"This is a really important game for everyone given that it is his (Burley's) first one in charge and everyone will be wanting to impress him. George will also want to do well in his first game to set the tone f or his management of the national side."
The 23-year-old Hearts captain has been in fine form this season and is hoping to make a strong impression on former boss Burley.
"I am not going along to make up the numbers in the squad. He has brought in some fresh blood and it's up to me to keep working hard, keep learning as much as I can and you never know, there might be an opportunity for me against Croatia.
"Only time will tell but it's every footballer's ambition to play for their country."
