Video: Stefan Kiessling's 'ghost goal'

Stefan Kiessling scored what proved to be the winning goal during Bayer Leverkusen's 2-1 victory over Hoffenheim in the Bundesliga last night.

However, replays showed that his headed effort was not on target and had actually gone in via the side-netting.

The referee failed to spot that, though, and allowed the goal to stand. You can watch the incident below.
