Viktor Kassai took his refereeing badge back in 1990. He has officiated in first division games since 1999, and on the international stage from 2003.

He refereed two matches last season including the 3-0 win over Puskas FC, and the 2-0 win against Paks. Kassai has already taken charge of two matches involving Vidi this season. Those were the games against MTK and Haladas.

He will be assisted by Gyorgy Ring and Vencel Toth for Saturday's match at Ujpest, which will kick off at 18:00pm. The fourth official will be Balazs Farkas.
