Former Melbourne Victory goalkeeper Mitch Langerak is hoping he can learn quickly at his new club with a little help from the number one.

The 21-year old recently signed a deal with the German Bundesliga club, replacing back-up keeper Marc Ziegler, and is now set to learn some new trick from 29-year old gloveman Roman Weidenfeller who has been with Dortmund since 2002.

"I have heard a great deal about the history and the successes of Borussia Dortmund,'' Langerak told the club's official website.

"I also know that Roman Weidenfeller is a fantastic goalkeeper and I would like to learn a lot from him.''

It reportedly took the Germans three attempts to sign Langerak with the Victory knocking back two offers, such is their desire to have him on their books.
