Pierre-Emerick Aubameyang has five goals from five goals this season.

And suddenly, he sees a target of 20 this season as very realistic.

The Gabonese forward has been key to Borussia Dortmund's quest to unseat Bayern Munich as champions of Germany so far, with the team having a perfect unbeaten record.

"We have started the season well, although everybody knows that Bayern are favourites, as I said, and I am probably the only one thinking this and others don't," Aubameyang says.

The 26-year-old has grown in stature as, after five weeks of Bundesliga football, Dortmund are top of the league. The latest was a win against Bayer Leverkusen on Sunday.

"I don't think that Bayern will win the league this season. At least, this is what I think."

The Bavarians have also won all five of their opening games, but are behind Dortmund on goal difference.

Aubameyang leads BVB's attack in the setup of new coach Thomas Tuchel. In fact, the former Saint-Etienne and AC Milan striker apparently has a bet with his boss.

"I want to score 20 goals in the Bundesliga this season," Aubameyang reveals.

"That's a target I want to achieve. I have a bet with the coach so I will give it my all in order to achieve this goal because I want to improve.

"It's not really a bet but at the end of the season I will show you something. I will have something to show but only at the end of the season.

"(Tuchel) has managed to make me feel at ease from day one. He gives me the confidence I need. He talks to me a lot. We speak in English but it's good for me to talk with him.

"We have many exchanges and we work a lot on this, on the videos and we do all this kind of things."

Dortmund and Bayern will clash in their first game of the season on October 4 at the home of the champions.
