Frank Mill must feel like Marty McFly, the main character from Back to the Future. Regardless of what he's up to, he is continuously being dragged back to the mid-1980s. To one day in particular: 9 August 1986.
It was Mill's first game for Borussia Dortmund. Just before half-time, he was played clean through. One pass split the Bayern Munich defence and, after dribbling past the keeper, he found himself in front of an empty goal. What happened next is often described in Germany as the 'miss of the century'.
Mill waited too long. With an open net in front of him, he took an extra touch to steady himself, slightly to the side of the six-yard box, delaying what seemed like the inevitable. As the keeper came rushing back, sliding in to make a hopeless attempt to block, Mill suddenly ran out of rhythm and the ball held up in his feet. When he finally did shoot, he hit the post. The ball bounced back to a waiting Bayern defender.
Even 35 years on, whenever anybody in German football misses a good chance, it doesn't take long for commentators to bring this story up. Reporters will call him asking for an opinion. The very act of failing to score from an open goal is known as 'a Mill'.
