In the 2004–05 UEFA Champions League, during the semi-final second leg match between Liverpool and Chelsea at Anfield in which the home team won by 1-0 and hence qualified for the Final, there was debate over whether a "ghost goal" had been scored by Liverpool winger Luis García. A computerised 're-enactment' suggested the ball had not crossed the line, and that Micheľ would have been unable to see it from his angle, while motion expert Mike Spann concluded that Micheľ had made the correct decision. Micheľ himself stated that his decision was based on the reaction of the assistant referee.
