Borussia Dortmund have left Pierre-Emerick Aubameyang out of their squad due to undisclosed "disciplinary reasons".

The Bundesliga club confirmed that the 21-goal striker would miss Sunday's game with Wolfsburg, their first match since the winter break.

Aubameyang is believed to be up for sale after several alleged spats with manager Peter Stoger and predecessors Peter Bosz and Thomas Tuchel.

According to Bild, the decision to omit the Gabon international from their latest matchday squad was taken after the player skipped a team meeting following training on Saturday.

Aubameyang missed a fixture against Stuttgart in November for similar reasons, while in 2016, he was dropped for an unauthorised trip to Milan.

Chinese Super League sides Guangzhou Evergrande and Beijing Guoan are believed to be keen signing Aubameyang, while Liverpool have also been credited with an interest in the marksman.
