The England international made his comments after his Borussia Dortmund side lost 2-1 against rivals Bayern Munich last weekend after a series of controversial decisions,
Dortmund says referee Zwayer wave away their calls for a penalty, before Robert Lewandowski scored the winner from the penalty spot after a hotly contested decision to award a handball against Mats Hummels.
Speaking after the match, Dortmund stars Bellingham and Erling Haaland didn't hold back in their views on referee Zwayer, in interviews with Jan Aage Fjortoft.
"It wasn't a penalty, (Hummels) wasn't looking at the ball, he’s fighting to get it. It hits him," Bellingham said. "You can look at a lot of the decisions in the game; you give a referee that has match-fixed before the biggest game in Germany, what do you expect?"
Striker Erling Haaland was similarly displeased by the official's display and, immediately after full-time, tweeted a thumbs-down emoji on a quote tweet of the announcement of Zwayer being appointed for the game.
“I think it was a scandal when it comes to the referee," he said. "Clear penalty (on Marco Reus in the first half). I asked (the referee) 'why didn't you just go and look?', he said 'there's no need', like an arrogant... no, I have to calm down a little bit now. He was arrogant and I will not say more."
Zwayer offered an insight into his decisions, telling Sky Germany: "It was contact in the upper body area, which is allowed to happen even at high speed.
"The situation is not black and white, I decided against the penalty kick because of my line [of sight]. It was not necessary for me because I had a clear view.
"Again, in the situation with the handball on Hummels I had a factual perception. In the other situation I had a complete view, if the video assistant had a second shot - like an arm that was out - he would have given me that on the ear."
Zwayer was banned from football for six months after reportedly accepting a bribe in 2005 - though confirmation of the ban did not emerge until several years later.
