For Real Madrid, the selection of the referee for the Champions League final is crucial, and this match's referee selection is somewhat delicate for Real Madrid.
UEFA announced yesterday the referee selection for the Champions League final at Wembley, and Hungarian referee Viktor Kassai will officiate the Champions League final.
The entire officiating team is from Hungary, with Gabor Eros and György Ring serving as the first and second assistant referees (linesmen).
The 35-year-old Viktor Kassai has officiated 5 Champions League matches and 1 Europa League match this season.
Since becoming an international referee in 2003, Kassai officiated the men's final at the 2008 Beijing Olympics, in which Messi's Argentina defeated Nigeria 1-0 to win the championship.
