Michas worked several high-profile matches, including four consecutive Greek Cupfinals from 1968 to 1972,[2] before being selected for European competitions. His performance at the 1973 European Cup Winners' Cup Final was widely criticized, leading to an investigation.[3] UEFA banned Michas from refereeing for life following the investigation.
In 2009, Richard Corbett, an MEP for Yorkshire and Humber petitioned UEFA for a reversal of AC Milan's victory over Leeds United in the 1973 final.[4]
