The 21-year old has bided his time in the past few seasons as number two to become first choice shot-stopper with the two-time champions and has not looked back since he got his chance earlier this season.
Langerak’s game has continually improved over the past few months and it culminated in his best-ever performance for the Victory on the Asian Champions League stage when he produced half a dozen top-shelf saves to deny Japanese club Kawasaki Frontale at Docklands Stadium on Wednesday.
With that performance but not on that alone, Muscat can see plenty of interest flowing in for the Queenslander and says it will be quite a task to keep the young gun at the club.
“It's going to be tough for the football club because I'm sure other people are noticing his stocks as well," he said.
"Not only is he a good keeper, he's a good kid and willing to learn and he's got a very big future.
“Mitch made some outstanding saves," Muscat added.
"He was super for us. It was probably fitting the way we won in the end was by an unbelievable save by Mitch because he was by far the best player on the park."
Langerak’s performance helped the Victory to their first win of the group stage and they still have a slight chance to progress to the Round of 16 providing they can notch up wins in the remaining two matches.
