The ticker showed the message for a number of seconds at around 9.35am this morning during a sports segment.
However, it was later revealed to be an intern doing training on how to use the ticker, who had accidentally published one.
The BBC anchor apologised two hours later and said: ""Ever so sorry, but we have a new intern training how to use the ticker.
"They did not mean to publish ‘Manchester United are rubbish’, and we are deeply sorry."
