England midfielder Bellingham was not alone in his frustration. Several Real players reacted strongly both during and after the match.
Defender Antonio Rudiger hinted his disapproval but stopped short of direct criticism.
“It’s best I don’t talk about the referee. Did you see the red card?” he told the media.
Club captain Dani Carvajal, who did not feature in the match, confronted referee Slavko Vincic from the touchline following the incident.
Television footage showed him shouting angrily and pointing towards the official after Camavinga’s dismissal.
“It’s your fault,” Carvajal is seen shouting.
Arda Guler, who scored Real’s first two goals, was given a red card in the aftermath of the defeat after storming over to the referee.
He wrote on Instagram after the game: “This isn’t how it should’ve been. We’re very sorry. We will be back. Hala Madrid.”
Guler will now miss the first game of next season’s league phase.
Manager Alvaro Arbeloa said the sending-off “obviously” decided the match, insisting: “You can’t send a player off for something like that.
“Nobody understands how a player can be sent off for that.
“I think the referee took out the card because he did not know Camavinga was booked already, because it was up to Bayern’s players to go and tell him it was the second card.
“It’s a double mistake besides not knowing he already had a yellow. It ruined a match that was going really well, very evenly matched. It was at its peak. That was the end of the game.”
Spanish journalist Juan Castro described the mood of those at Real as one of disbelief.
“People are very angry at the referee,” he said. “They are very worried about what has happened in Munich. This will have consequences.
“The second yellow card to Camavinga, you cannot give it in a Champions League match at that moment, when both teams are level. You cannot give it.
“You could see all the players going against the referee. From Madrid’s perspective, that decision shifted the balance to Bayern Munich.”
