European Cup winners of 1967, Celtic went to unknown Artmedia Bratislava in the first leg knowing any kind of result should be enough before the home leg.
Instead theu suffered a 5-0 thrashing in what manager Gordon Strachan described as 'out-and-out the worst football night' he had ever experienced.
Celtics biggest defeat in European history against a team that had never competed in Europe was a disaster for the Scottish giants.
Despite a 4-0 win in the return leg it was not enough to overcome the deficit and they crashed out.
