The Germany international committed a major faux pas as he wore a Nike T-shirt for his unveiling, despite Bayern being sponsored by Adidas, who also have a 9.1 percent stake in the club.
Gotze angered Dortmund supporters when his £32 million move to Bayern was revealed in the wake of the defeat of Malaga in the Champions League quarterfinals, which sent Jurgen Klopp's team into the last four.
But as he was unveiled to the German media on Tuesday, Gotze clearly hadn't researched his new employers too much and wore a Nike top.
In September of 2011, Gotze signed a lucrative deal with Nike worth around £1.3 million a year to the player, according to German newspaper Bild (via Goal.com).
The mistake might have been a funny moment for the vast majority of supporters, while the publicity generated for both companies from the incident should offset any embarrassment caused by the midfielder's choice of garment.
We are now looking forward to new Bayern coach Pep Guardiola pitching up in front of the media wearing Hi-Tec trainers.
