Mönchengladbach - Borussia Mönchengladbach have extended the contract of winger until 2019.
Herrmann has put pen to paper on a new deal that will see him represent the Foals for the next four seasons.
"We're delighted that we've been able to tie Patrick down here and that he wants to continue with us along the successful path we're following," said Gladbach's sporting director Max Eberl. "Patrick has developed from a youth player to a Bundesliga player with us and we're pleased that he wants to take the next step in his career here."
Herrmann has made a total of 185 Bundesliga appearances for the Foals since making his debut just over five years ago and has found the back of the net 35 times, including eight this season. "I really enjoy playing for Borussia and I feel the club and the bosses have faith in me," said the 24-year-old. "We've got great fans and a unique stadium. I feel at home here and these are things I need to be able to progress in my career, including returning to the national team."
Hungry for more in Europe
Herrmann's excellent form this term has helped Borussia push for a place in the UEFA Champions League next season. With ten games of the season remaining, they sit third in the standings with a two-point advantage over fourth-placed Bayer 04 Leverkusen and an eight-point cushion over FC Schalke 04 in fifth.
"I still have some big goals with Borussia. Our games this season in the Europa League gave us a taste for more, and I'd like to be successful with the club at home and in Europe," added Herrmann, who has also scored four times in Europe this season and helped Gladbach reach the quarter-finals of the DFB Cup with his strike in the last 16 against Kickers Offenbach.
Gladbach to the core
Herrmann arrived in Mönchengladbach in 2008 from 1. FC Saarbrücken, moving into the club's youth academy. At the age of 18, he broke into the first team and made his debut in January 2010. He made 24 appearances in his first full season as a professional and despite suffering a setback with a broken collarbone, he helped the Foals qualify for Europe in 2011/12.
His performances in the following campaign, in the Bundesliga and Europa League, saw him move onto Germany coach Joachim Löw's radar, but despite being included in die Nationalmannschaft's squad once before, Herrmann is yet to make his senior debut at international level.
