Borussia Dortmund left-back Erik Durm has put pen to paper to extend his contract at the Bundesliga runners-up until 2019.
Durm is one of the five World Cup winners in the Dortmund squad, and was one of the major surprises before the tournament in Brazil when he was selected by Joachim Low ahead of teammate Marcel Schmelzer.
The 22-year-old has enjoyed a meteoric rise into the Dortmund first team, starting as an attacker in the club's reserve side at the beginning of last season before being converted into a versatile full-back by Jurgen Klopp.
Following a total of 29 appearances for Dortmund in all competitions, he was called up by Low in May 2014, and is set to start for Germany in a replay of the World Cup final against Argentina on Wednesday.
"He's proved himself in Brazil, and has the advantage that he's currently starting games for Dortmund," Low said on Tuesday.
Previously tied to Dortmund until 2017, the left-back extended his contract for two more years, and was praised by the club's sporting director Michael Zorc after putting pen to paper.
"Erik is a great, down-to-earth young man who fits in perfectly at Borussia Dortmund. It was obvious to us that we would reward his excellent sporting development and extend his contract long-term," Zorc told the club's official website.
Durm said that he was keen to reward the club for the faith they had placed in him and admitted that he was excited by the Westfalenstadion outfit's future plans for success.
"Borussia Dortmund has driven my development so intensively that I have become the player I am today," he added.
"It goes without saying that I value that immensely and want to commit myself long-term to the club that has nurtured me. I have the upmost faith in the path BVB is taking. We are steadily building something fantastic here and I want to be a part of it for as long as possible."
