Borussia Dortmund striker Pierre-Emerick Aubameyang was dropped for the Champions League clash with Sporting Lisbon on Wednesday after reporting back to training late following a private trip to Milan, according to German media reports.
Aubameyang, 27, was surprisingly left out of the Dortmund squad for the 1-0 victory over Sporting because of unspecified "internal reasons" and had to watch on from the stands.
German news agency dpa, alongside two other media outlets, claim the Gabon international's suspension was imposed by the club after he flew on a private jet with friends to Italy on Monday and reported late for training on Tuesday. Dortmund did not train on Monday.
The German club won Wednesday's game thanks to a goal from Aubameyang's replacement, Adrian Ramos, and advanced to the round of 16 off the back of the result.
Dortmund coach Thomas Tuchel said Aubameyang would be back in the squad for the Bundesliga match against Hamburg on Saturday.
