Norwich City completed the signing of FC Augsburg midfielder Moritz Leitner on Thursday on a loan deal until the end of the 2017-18 season.
Born in Munich in December 1992, Leitner signed for 1860 Munich at the age of six and rose through their youth ranks to make his first-team debut in 2010.
Having represented Austria at Under-17 level, he switched allegiance to Germany after receiving citizenship and made his international bow for the Under-19s in 2010.
A series of eye-catching performances caught the eye of Borussia Dortmund, with Leitner joining Der BVB in January 2011 at the age of 18.
He was immediately sent on loan to FC Augsburg and helped them win promotion to the top tier of German football for the first time.
In the summer of 2011 he returned to Dortmund, and was also called up by Germany's Under-21s for the first time.
He made 20 appearances for Dortmund during the 2011-12 campaign, helping them to a historic Bundesliga title.
The midfielder also featured in three Champions League matches, including coming on as a first half substitute against Arsenal at the Emirates.
He featured 29 times during the following season, notably being named on the bench for Dortmund's Champions League final defeat to Bayern Munich at Wembley.
Leitner spent the next 24 months on loan at Stuttgart and was also awarded the captaincy of the country's Under-21s squad.
Returning to Dortmund for the 2015-16 season, Leitner was limited to 13 appearances by the form of Ilkay Gundogan, Shinji Kagawa and Gonzalo Castro.
In 2016, he left the Bundesliga to join Lazio in Serie A for a brief spell ahead of returning to Augsburg on a permanent deal in January of last year.
