What else is more embarrassing than the fact that Derby's mortal enemy is on his own court? The Holland striker FARFAN, who struck a record price to Schalke 04, has caused such an incident.

He missed two training sessions two days later and explained that when he was detained by the police at the airport, he was more unacceptable to the 04 fans. He even appeared in the training ground wearing Dortmund sneakers.

Valfan wore a yellow black Nike sneaker (model: Nike Total 90 Laser II, priced at 185 euros), while Huang Heizheng was the color of Dortmund's 04 deadly enemy. Nike was a former sponsor of the Dortmund club. Schalke's 04 official sports equipment sponsor was Nike's rival Adidas.

Peters, the 04 manager of Schalke, explained: "there is a two-year contract between Nike and Adidas. I have clarified the Adidas official. Maybe he will be the only player in the team wearing Nike shoes."

However, because FARFAN and Schalke 04 club signed a contract, which means that after two years of contract with Nike, FARFAN will not renew the contract with the other side.

"FARFAN will wear Adidas shoes in two years."

Peters said.
