Pierre-Emerick Aubameyang: Borussia Dortmund drop striker for disciplinary reasons

Pierre-Emerick Aubameyang scored 31 times in 32 Bundesliga appearances last season

Borussia Dortmund striker Pierre-Emerick Aubameyang has been dropped for disciplinary reasons.

Reports in Germany said the 28-year-old was late for training, but Aubameyang says he was "baffled" by the decision.

Aubameyang will not be considered for the Bundesliga game against VfB Stuttgart on Friday.

Dortmund announced the suspension in response to a supporter's question on Twitter, but did not elaborate on the reasons behind it.

Gabon international Aubameyang was also suspended by his club last year for an unsanctioned trip to Italy.

"I could understand why I was suspended for Milan because I did not respect the rules, but this time I am truly baffled. I did not want to arrive late," he told German newspaper Bild.

Dortmund have lost three of their past four league games to drop to third place in the table, six points behind leaders Bayern Munich.

They host Tottenham Hotspur in the Champions League on Tuesday.

Aubameyang, who was linked with summer moves to Chelsea, Manchester City and Paris St-Germain, was absent from a video tweeted by the club showing the squad as they arrived at the airport to fly to Stuttgart.

He started this season by scoring 15 goals in his first 12 matches, including two Bundesliga hat-tricks, but he has since gone 476 minutes without scoring.
