For reference about the referee I mentioned earlier...
Felix Zwayer accepted a $300 bribe to help an extremely corrupt referee named Robert Hoyzer fix a match, and then he later snitched on him when Hoyzer was being investigated.
Since then, Zwayer has been blatantly lying about his involvement in bribery and the testimony he gave. According to his testimony, Hoyzer unsuccessfully offered him bribes multiple times and showed him large amounts of cash.
Yet in public, Zwayer claims he never accepted a bribe and had no knowledge of any prior attempts to fix matches. Which is the polar opposite of his own testimony in the investigation, and his "I never accepted a bribe" shtick is just playing semantics.
Due to the lack of any paper trail and cooperating against Hoyzer, he was only suspended 6 months for not refusing a bribe, rather than accepting a bribe. So he uses that to play semantics and act like he's just an honorable man who immediately alerted authorities about being offered a bribe, which isn't the case either. He did voluntarily contact investigators to cooperate but only after reports of Hoyzer being under investigation.
Bellingham was actually fined at Dortmund for saying something along the lines of 'what do you expect from a match fixer' after Zwayer made a controversial penalty call for Bayern that gave them a late win over Dortmund.
