Moss: Langerak loving life at Borussia Dortmund
The two goalkeepers were together last season at Melbourne Victory.
Langerak made his first team debut on Saturday in victory over Bayern Munich and Moss told tribalfootball.com: "Mitch and I were great mates at the Victory.
"He's a really good kid with a strong work ethic. It's not surprised me he's gone on to bigger and better things. We stay in touch and I know he's loving life at Dortmund.
"He says he's never worked so hard!
"I expect him to be in the (Australia) national team set up very soon."
