Pierre-Emerick Aubameyang was dropped from Borussia Dortmund’s Champions League match on Wednesday against Sporting Lisbon for disciplinary reasons.

Aubameyang made an unsanctioned trip to Italy on Monday to attend a party about 60 kilometers from Milan.

"I have nothing to say," Aubameyang told Bild.

Aubameyang will return for Dortmund's match this weekend.
