Description: Felix Zwayer had not been an unknown name in Germany, before he joined the DFB top level. He made a big contribution to the German match-fixing scandal's solving as he immediately reported some strange odds he observed in the contact with Robert Hoyzer who came from Berlin as well. Zwayer is member of a Bundesliga club: Hertha BSC Berlin. After he had been the regular assistant referee of FIFA referee Manuel Gräfe in 2007 and 2008, he was promoted to become a new Bundesliga referee. His first seasons were very impressive, he always showed a very lenient style and proved himself to be a referee who does not like showing too many cards. Nevertheless, one has to state that this led to some unlucky decisions as he refused three times to issue obvious red cards for professional fouls.
