Hungarian official Viktor Kassai will take charge of Tuesday's Champions League encounter at the Allianz Arena - his second Barca clash of this year's tournamentUefa has appointed Hungarian referee Viktor Kassai for the Champions League semi-final first leg between Bayern Munich and Barcelona.
Kassai has established a strong reputation for himself in recent years, officiating in both Euro 2012 and the 2010 World Cup, and became the youngest man to referee a top-flight game in Hungary at the age of 23 in 1998.
The 37-year-old will be assisted by an all-Hungarian team, including Gabor Eros, Gyorgy Ring, Robert Kispal and Tamas Bognar - all of whom were officiating when Barcelona overcame Manchester United 3-1 at the 2011 final at Wembley - while Mihaly Fabian completes the line-up.
In addition to 2011's final, Kassai also refereed the Blaugrana's 4-0 Champions League last-16 win over AC Milan in March, so Catalunya may consider him something of a lucky omen - although his appointment is unlikely to be welcomed in Munich.
The Hungarian took charge of last season's semi-final between the Bavarians and Real Madrid, and awarded a controversial penalty against David Alaba for a perceived handball, with the ensuing booking ruling the defender out of the final against Chelsea. Luiz Gustavo and Holger Badstuber were then issued yellow cards in extra-time, also ruling them out the final at the Allianz.
Kassai has overseen five Champions League games this season, showing 27 yellow cards and no reds.
