Old Trafford was at its raucous best on Sunday as Manchester United booked their place in the FA Cup semi-finals with a dramatic 4-3 extra-time win over Liverpool. Erik ten Hag's side were both 2-1 and 3-2 down but goals from Marcus Rashford and Amad Diallo set off wild celebrations.
It's been a relatively underwhelming campaign for United, who were knocked out of the Champions League and Carabao Cup before Christmas, but supporters have remained loyal and flocked to Old Trafford in their thousands at every opportunity. It is why the Theatre of Dreams remains one of Europe's most iconic grounds.
But amid all the modern, state-of-the-art grounds across the continent, how well does it rank in terms of attendance? Well, Transfermarkt have collated the data to rank the average attendance of each European club's league matches. Take a look below to see where United rank.
