Gabonese international Pierre-Emerick Aubameyang would certainly be in for an earful after his latest haircut seemed to upset Club directors after promoting club sponsor's rival.
The BVB forward had a haircut that appeared to promote Personal Sponsor Nike during the club's 6-2 win over Bayer Leverkusen. The hair featured a pink Swoosh and Club Directors are hoping to put an end to the trend.
Puma is a majority shareholder and provides team kits for the Bundesliga club and sporting Director Michael Zorc is not willing to see a repeat.
"This will be certainly be from his personal sponsor, if my interpretation is correct," Zorc told Sky
"This will be hopefully be a one-off occasion, we will certainly address it in talks with him"
Dortmund have yet to fine Aubameyang for the incident and it remains unclear whether he will face action.
The striker was on the scoresheet in the weekend's game grabbing his 20th and 21st goals of the season taking him two clear of Bayern Munich attacker Robert Lewandowski in the league and ahead of the Polish player on Dortmund's all-time goal scorer list with 75 goals in 118 for the club.
