bundesliga.com has duly unearthed ten snippets of background information on BVB's man of the moment and happy-go-lucky Socceroo...
Growing up in Queensland, Australia, Langerak inevitably dabbled in a bit of cricket and rugby, before shifting his focus to football at the age of eight. Ten years later, following spells at local amateur outfits Tieri Tigers and Bundaberg Waves, the budding shotstopper was picked up by the renowned Australian Insitute for Sport (AIS), which nowadays counts Bayer 04 Leverkusen's Robbie Kruse amongst its distinguished alumni.
Unlike Kruse, whose first port of call as a professional was with Brisbane Roar, Langerak moved straight to Melbourne Victory after just a season at the AIS. The 1.91-metre custodian was loaned out almost immediately to South Melbourne, eventually making his debut for his parent club in a 2-2 draw with Sydney FC on Matchday 21 of the 2007/08 campaign. Two years down the line, he had made the no.1 jersey his own.
With A-League Premiership, Grand Final and Pre-Season Challenge Cup winners' medals under his belt, Langerak joined Dortmund on a four-year deal in summer 2010. The Bundesliga club had reportedly had two offers turned down before finally persuading the Victory to part with their prized last line of defence, who jumped at the chance to further his understanding of the game in Germany's acclaimed top flight.
While Langerak knew exactly what lay in wait at the Signal Iduna Park, his mentor Jürgen Klopp wasn't quite so sure. "You think you are going to get some beachboy from Australia, but what we actually got was a really hard worker," Dortmund's head coach recalled. "Mitch improves almost by the minute and is a born fighter. In goal is one position where, should we get an injury, I have no concerns about cover."
BVB's diligent Socceroo had to wait until 26 February 2011 to step into the breach, taking his first-team bow against the might of FC Bayern München at the Allianz Arena no less. The Queensland native was beaten once on the night, but it was BVB who ran out 3-1 winners en route to collecting their first league crown in nine years. Langerak's Bundesliga journey was at long last up and running.
Dortmund's No2 received his first senior international call-up to the Australian national team on 29 March 2011, albeit ultimately as an unused substitute in a 2-1 defeat to Germany. His debut came over two years later against France on 12 October 2013, but it perhaps wasn't quite the premiere he had hoped for, with Bundesliga megastar Franck Ribery among the goals in a comprehensive 6-0 defeat.
Bayern's French maestro must have had die Schwarz-Gelben's double-winning campaign of 2011/12 on his mind when he lined up opposite Langerak in Paris. The Dortmund man made his fifth appearance of that self-same season in historic Berlin on 12 May 2012, replacing Weidenfeller 32 minutes into BVB's eventual 5-2 DFB Cup final success over, you guessed it, Ribery's band of Munich brothers.
2012/13 wasn't quite such a joyous occasion, though, as Bayern responded to two years spent in BVB's black-and-yellow shadow with an unprecedented league, cup and Champions League treble. Langerak, for his part, made just three appearances in all competitions that year, helping his side record hard-fought Bundesliga wins over Bayer Leverkusen, FC Augsburg and Fortuna Düsseldorf.
The Australian international's impressive record of never having lost a game in Dortmund colours came to an end on 18 September 2013 against SSC Napoli in the Champions League. In his defence, Langerak only entered the fray in place of Weidenfeller (who had been sent off) at half time, and it wasn't until Matchday 1 of the 2014/15 campaign against Bayer 04 that he suffered his first defeat in 16 starts in all competitions for the club.
So what does the man himself make of life in the ? "I'm very happy where I am and the club are happy with me as well," explained the 2014 FIFA World Cup goer, who regularly meets up with fellow Aussie star Kruse whenever time permits. "The preconceptions the Germans have about us Australians are spot on. After training I chill out, drink coffee and hang out."
