Stood down from refereeing after receiving death threats amid Uefa's condemnation of Jose Mourinho's allegations that Frisk was in cahoots with Frank Rijkaard during Chelsea's game at Barcelona. It is such a shame, considering he is one high-calibre referee. These are hard to find in our scandal-plagued world.
As a result of these allegations, Jose Mourinho was fined by Uefa and suspended for 2 matches. Chelsea beat Bayern over 2 legs without him watching from the touchline or tongue-lashing the players in the dressing room.
According to an earlier thread, he was slightly injured by a projectile thrown bya Roma fan during the group stage game with Dynamo Kiev. The game was then abandoned and Kiev were awarded a 3-0 default win.
