The 19-year-old is coming off a dream debut season with Rosenborg BK, the club cruising to the league title last month.
Gersbach made 19 appearances in the Norwegian Tippeligaen and became a key figure late in the season.
Following next week’s qualifier in Bangkok, Gersbach will head back to Norway for the Norwegian Cup Final against Kongsvinger Rosenborg could secure the double for the second straight season. “We’ve got some history in the making hopefully,” an upbeat Gersbach told FFA TV. “If we do win the double again this year…it will be the first time in Norwegian history a team has won the double two years in a row. “It’s been a really exciting season for me. Coming into the [Rosenborg] team in February, having short little season and then getting straight into it,” he added. “It’s been a really successful season for us.”
And it caps what’s been a remarkable 12 months for the teenager after leaving Hyundai A-League club Sydney FC to sign a three-year deal in Scandinavia.
As well as his club success, Gersbach has made his international debut with the Caltex Socceroos against Greece and is battling with AFC Bournemouth’s Brad Smith for a starting spot against Thailand.
Meanwhile Gersbach and Caltex Socceroo team-mates Bailey Wright, Adam Federici and Nathan Burns took time out from their preparations to attend a junior football clinic in Bangkok on Wednesday.
The quartet put 40 young Thai kids through a mini session before heading off to training at the SCG Stadium.
“These little kids were maybe between the ages of seven and 14 and they were pretty impressive. Me and Bailey were in awe of some of their skills, we were struggling to tackle them,” Gersbach said.
But the former AIS player knows things will be much tougher on Tuesday night as the Caltex Socceroos chase another crucial three points on the Road to Russia 2018.
While Australia is unbeaten after four games, Thailand are yet to register a point despite some impressive displays.
“I’m expecting the Thais to be pretty good, pretty sharp and pretty skilful but we should have enough power and enough of a game plan to get past them,” Gersbach said.
“100% we want three points out of this game. We took two points out of the last two games which, wasn’t a bad result, but we need three points from this game and we’ll be searching for nothing less.”
