WATCH: Mario Gotze commits embarrassing PR own goal at Bayern Munich presentation
SOME footballers aren't immune from the proverbial shooting themselves in the foot and Mario Gotze certainly did that.
At his official presentation as a Bayern Munich player, Gotze committed the cardinal sin of posing in a Nike shirt while holding the club's new Adidas-made shirt.
Adidas have a long-standing relationship with Munich and have a 9% stake in the Bundesliga powerhouse.
Though the £31.5m signing's wears Nike boots, he incurred the wrath of Adidas for breaching their rules of attire for official Adidas functions.
"The pictures taken at the Mario Götze press conference have surprised us, negatively," Oliver Bruggen, a spokesman for Adidas, told German paper Bild.
"Contractually it is not allowed: this was an official function of Adidas partners Bayern."
