A Borussia Dortmund fan (we hope) has been arrested and banned after breaking into the club's ground for a kickabout in his birthday suit, reports the Sun.

According to police, a naked 25-year-old was caught by censors after trespassing onto the pitch at around 8:30 p.m. on Tuesday to fulfill a lifelong dream.

We know what you're thinking; Germany in December isn't known for its tropical climate.

But rest easy, because police spokeswoman Dana Seket told the press: "He told us that he had become very warm through the game."
