Borussia Dortmund star Karim Adeyemi has revealed why he wears special shin pads, which reference the popular anime series One Piece.

Dortmund sits atop the Bundesliga table ahead of the final game of the season, enjoying a two-point lead over Bayern Munich.

It would be their very first league title since 2012 if they were able to win their final game of the season.

Edin Terzic’s side will host FSV Mainz at home on Saturday, while Bayern faces FC Koln.

Adeyemi, who moved to the German side from Austrian club Red Bull Salzburg for a deal worth €38 million last summer, has scored six goals and made five assists in 12 Bundesliga games.

Adeyemi became a talking point among football fans with a passion for anime when a picture of his shin pads went viral.

The Guards feature Monkey D. Luffy, the lead character in the Japanese anime television series One Piece.

The forward said they are designed for him and that they feature the flags of his heritage, Nigeria and Romania, where his father and mother are respectively from.

“They are shin pads designed specifically for me,” Adeyemi told the Bundesliga’s official newsletter.

“I have the national flags of my heritage on them—one pair with Nigeria and the other with Romania. I also have the character Luffy from the One Piece anime on them. He is my favorite character from the series, so I always play with these shin pads.”
