Pierre-Emerick Aubameyang has confirmed he has signed a contract extension at Borussia Dortmund, backing up media reports last season's Bundesliga leading scorer had put pen to paper on a new deal.

German media reported on Sunday Aubameyang had added a year to his contract at the Signal Iduna Park, taking him through to 2021 with Die Schwarzgelben.

The 28-year-old, who joined Dortmund from French club Saint-Etienne in 2013, stated in a tweet that he had in fact inked a fresh agreement some time ago, but that the information had not filtered through to the media.

"Let me listen to music, it's better than the newspapers!" Aubameyang wrote, accompanying his post with a picture of himself wearing headphones. "It's a bit of time since I extended my contract. But it's not your fault, you didn't know. Just like usual."

Zorc: 'We're planning with Auba'

Aubameyang, who has scored 13 goals in 15 league games for BVB this season, has been linked with a number of other clubs throughout his time in the Ruhr, notably Real Madrid, the club the Gabon captain has admitted supporting as a boy.

The club has so far resisted all suitors for their star forward, and appear determined to continue doing so.

"Clearly we're planning with Auba. He has a very long-term contract in Dortmund. He'll leave Dortmund at some stage, but for us he's an extremely important player and we're planning on moving forward with him " BVB sporting director Michael Zorc told Sky Sports Germany on Sunday.

"Auba is an extraordinary player, not only because he scored 19 competitive goals in the first half of the season. He's extravagant, a colorful character. It does a town like Dortmund good."

Zorc: 'Total top-class pro'

The former AC Milan youth academy reject's spectacular form on the pitch means he gets some leeway from the club's hierarchy, though they will attempt to rein in an issue that has caused some dischord in their otherwise harmonious relationship.

"We have a problem, that is punctuality. That I must say quite clearly," Zorc continued. "That has crept in in the last year, that he came late more often than not.

"His mate [Ousmane] Dembele was also involved in that. Then, as a club, you have a problem of how you deal with that. Other than that, he's a total top-class pro. I don't think we'll ever totally solve that, but we can deal with it well."
