The 27-year-old joined BVB from Saint-Etienne in 2013 and his displays at the Westfalenstadion have seen him linked with a number of top clubs in Europe.
The Gabon international signed his latest deal in July 2015 and is due to ply his trade with Dortmund for another three-and-a-half seasons.
He admits that playing in front of the home faithful is a special experience, with the 25,000-strong “Yellow Wall” on the stadium’s Sudtribune enough to lift any player.
“The fans of BVB are really incredible, it’s hard to describe what you feel when you play in front of them,” he told Soccer Laduma.
“The atmosphere they create, not just with the ‘Yellow Wall’, with the 25,000 fans present in each game, but for the whole 90 minutes, regardless of the result or the opponent.
“There are many things that the fans and the city of Dortmund generally appreciate. All of this has contributed to the decision to extend my contract to 2020 and I can imagine staying even longer.”
