In her column for The Sun, Brady, who is a former managing director at the club where Bellingham started his career, Birmingham City, reflected on how criticism of referees has become an ingrained part of football culture.
"Fierce criticism of referees is practically a national habit, either in stadiums or at the TV. And why not? If we wish to send hot air at such targets and without much chance of reprisal, well, good luck to us," she wrote.
She then questioned whether Bellingham had crossed the line with his remarks.
"Did Real Madrid’s Jude Bellingham stray too far when he muttered 'f*** off' or 'f*** you' in the direction of referee Jose Luis Munuera Montero?" she asked.
"The hugely talented 21-year-old says it was directed at himself. The ref said it was aimed at him and he had the red card! Bellingham is no innocent Brummie abroad. He has been sent off as a Real player once before and should know that while 'f*** off' is often aimed at someone’s own failings, it can easily be misunderstood. There is a much bigger aspect to this. On-field reaction to rulings might be generally overlooked. In the real world, not so much. No one expects going to a match to be like attending church, but some of the bile delivered at refs and players is gruesome."
