The 22-year old former Oakleigh Cannons man has been one of the surprise packets of the season so far, performing with consistency and assuredness with the A-League's newest club, but he knows that he has to keep his feet grounded and continue in the same vein for his early-season form to mean something.
"I've been pinching myself ever since I came to the club and I'm very humbled to be among the players I am here," Kalmar said.
"The coaching staff have had a lot of faith in me and telling me to go out, and that I have nothing to lose. I go out every game with that attitude."
Kalmar has been pulling the strings in midfield in the past few weeks for the Heart and his 11th minute goal against the North Queensland Fury on Saturday helped the club to their first win. It came just a week after he netted in the 2-2 draw with Perth Glory and his recent showings so far have helped his side jump to 6th on the table.
