Australian captain Pat Cummins has encouraged teen batting prodigy Sam Konstas to go confident on his Test debut infront of a packed crowd at the MCG.

Sam Konstas will be Australia's youngest ever Test opener and will slot into number 4 in the overall age list. But Pat Cummins has shown his support to the squad's youngest member to go well.

"I said this to Sam the other day; I remember as an 18-year-old I was thinking I've got a lot more leeway because I was young," Cummins said. "I almost felt like if I didn't have a great game it wasn't my fault it was the selectors' fault for picking me. It was like, they're the idiots who picked an 18-year-old. You are so young starting out your career, it's Boxing Day, it doesn't get any better than this so just enjoy the moment.

"I spent a bit of time wondering why or how I was there, how it had happened so quick. I just remember being really excited and it's similar to Sammy this week. There's a level of naivety that you just want to go out and play like you do when you are a kid in the backyard - take the game on, have fun, and not overthink it.

"That's the message to Sam. That's definitely how I felt as an 18-year-old, just really excited, and once the game started you go into game mode and it's just like any other game."
