With 15 goals in all competitions this season, we should be talking about Pierre-Emerick Aubameyang's reputation as one of the deadliest strikers in Europe.

Unfortunately, he's once again hit the headlines for the wrong reasons.

Ahead of Friday night's game against Stuttgart, Borussia Dortmund announced that the Gabon international had been suspended, though the Bundesliga club declined to specify the reasons.

Instead, BVB stated on Twitter that "disciplinary reasons" had seen him dropped.

This won't come as much of a surprise to Dortmund fans, as it's almost exactly a year since he faced a similar punishment for a Champions League game against Sporting Lisbon.

However, on this occasion, it's a little unclear what exactly it is that he's done to upset club officials.

There are conflicting reports. First, Bild stated that he had been late to training three times in a week, and that to top it all off, he took a trip to Barcelona to see former team-mate Ousmane Dembele without Dortmund's say-so. Never a wise move considering the bad blood there.

Rather than getting his head down, he then issued a statement to the newspaper, explaining:

"I could understand the punishment when I went to Milan [in November 2016]. This time, I really don't understand it. I didn't want to be late for training."

Auba's unauthorised video 

According to Kicker, another German publication, there is more to it than that. Aubameyang also stands accused of filming a video with freestyler Sean Garnier on club grounds; the shoot wasn't officially authorised, hence why the player has landed himself in hot water again.

To make matters worse, Garnier is sponsored by Red Bull - backers of Bundesliga RB Leipzig, so it's unsurprising that the incident hasn't gone down well.

Only club staff are allowed at the athletics hall and had Dortmund been asked to sanction the video, they would have said no because they don't allow private bookings within two days of matches.

Given that the forward hasn't scored in his last five matches, perhaps Peter Bosz won't miss him too much. Indeed, as he spends so much time trying to engineer a move away from the Westfalenstadion, they must have a contingency plan in place for when he's not available.

It has to be said, though, that these latest antics aren't going to put him in demand among Europe's elite clubs.

Should BVB sell Aubameyang next summer? Have your say in the comments.
