Hungarian referee Viktor Kassai will officiate the Champions League final between Barcelona and Man Utd.

Kassai is youngest ever referee for showpiece event

Hungarian referee Viktor Kassai will officiate this weekend's Champions League final between Barcelona and Manchester United at Wembley. The 35-year-old will become the youngest referee in the history of Champions League finals, surpassing record holder Pierluigi Collina, who was 39 when he took charge the showpiece event. Tamas Bognar and Mihaly Fabian will be Kassai's assistant referees at Wembley with Istvan Vad the fourth official. The two additional assistant referees are Mihaly Fabian and Tamas Bognar and Robert Kispal will act as a reserve. Kassai has been a member of Fifa since 2003 and he officiated at the 2010 World Cup finals. The Hungarian encountered Sir Alex Ferguson's side earlier in the season when he took charge of their 1-0 victory over Valencia during the group stages when he brandished only a single yellow card. He might be best known to England fans after taking charge of the Three Lions' win over Bulgaria in September 2010.
