Fans expressed their disgust as a banner was flown over the Etihad Stadium with the words 'British to be minority' on it during the Liverpool and Manchester City match.
The plane attracted attention during the Premier League match, which ended 2-2, as many fans took to Twitter to share images and videos of the banner. Some fans also called for the pilot of the plane to lose his licence.
"British To Be Minority By 2066" was the wording on the banner, with a photo circulating online during the first half, the Mirror repots. One viewer said: "words fail me", while another claimed the message "Makes absolutely no sense whatsoever."
