Davidson starred in his A-League debut on Sunday, with his relentless running a highlight of Glory's 1-1 draw with Western Sydney.

The left-back was just 22-years-old when he started in all three games for Australia at the 2014 World Cup in Brazil.

He was also part of Australia's Asian Cup-winning side in 2015.

But his international career has stalled since then and he hopes Glory coach Tony Popovic can help propel him back into the Socceroos' set-up.

Davidson had a brutally honest chat with Popovic upon signing with Glory.

Popovic has always rated Davidson but felt the 27-year-old was carrying too much weight.

Davidson has worked tirelessly to fix that over the past three months.

"Since I've come I've lost five kilos," Davidson said.

"I've been drinking a lot more water and eating smaller portions.

"I feel a lot better for it. I feel healthier, stronger, faster, quicker."

Davidson has played in Croatia, Portugal, the Netherlands and England during his well-travelled career.

But he jumped at the chance to link up with Popovic when the master coach arrived at Glory.

"The biggest reason I came here was to work under him," Davidson said.

"His attention to detail is unbelievable, and that makes the difference.

"He's a hard task master but he's simple as well. What you see is what you get with him.

"He's tough on me and I appreciate that.

"If you work hard and put your body on the line for the team he's the type of coach that rewards that behaviour."

Glory skipper Diego Castro (hamstring) and former Socceroos defender Matthew Spiranovic (hip surgery) were among five players who missed the draw against the Wanderers.

The duo will be assessed at training this week to determine their availability for Sunday's clash with Melbourne Victory at AAMI Park.
