According to CIES Football Observatory, Borussia Dortmund have the highest average attendance in World football, with an astonishing average of 80,000 people attending matches at the Signal Iduna Park in the years 2013 to 2018.
Old trafford is the second most visited ground, with Barcelona's Nou Camp, Bayern Munich's Allianz Arena and Real Madrid's Santiago Bernabeu completing the top 5.
Other notable mentions include Arsenal in 7th, Manchester City in 12th, Liverpool in 21st, Chelsea in 33rd and Tottenham in 34th. Atlanta United are the highest non-European club and they are 10th on the list.
Rather astonishingly, Sunderland have the 38th highest average attendance despite playing in League 1, and are ahead of the likes of Italian giants Juventus, Napoli and Roma, with Lyon, Everton and Valencia also coming behind the League 1 side.
