Bayern Munich skipper Phillip Lahm has lashed out at Nike for allegedly asking Mario Gotze to wear one of their t-shirts during his presentation.
The Bavarian giants, who are contracted to German-based brand Adidas, were stunned when their €37 million signing and defender Jan Kirchhoff appeared at their press conference wearing t-shirts emblazoned with Nike logos.
Subsequently, die Roten have decided to fine both players, but Lahm is adamant the sponsor is to blame and is convinced his new team-mates have been manipulated by their sponsor.
"I don't want to allege Mario and Jan of having bad intentions," the 29-year-old told Sport Bild.
"But I rather think that the players have been ordered by their sponsor to wear the t-shirts at their presentation.
"They just do what what they've been told without considering they and the event have been used for a third-party cause.
"This type of marketing contradicts with the contract of our long-term partners Adidas and does not comply with the term of Bayern Munich."
Gotze was unveiled by Bayern on July 1 after joining from Dortmund, while Kirchoff arrived on a free transfer after spending the last five years with Mainz.
