Since utd had the highest average attendance of over 48,000 when they were relegated and playing in division 2 which was the highest in the country, and also had the highest average attendance in the country every year that Atkinson managed us then I'm not going to bother carrying on with this debate.
I will end with the fact that if you think Liverpool would average 75,000 in a 75,000 stadium then I think your dreaming. They would certainly fill it out for the big games, but doubt they would average that. Man utds attendance on the other hand would have an average attendance of greater than 75,000 if the stadium could hold more than that.
