That's because Spanish giants Real and Barca, who according to the likes of Gary Neville are leaving their English rivals behind on the pitch, have more than three times as many worldwide followers on social networking site Twitter.
A new report by Inside World Football shows the Spanish duo, who with the likes of Cristiano Ronaldo and Lionel Messi in their ranks boast a collection of some of the finest players on the planet, top the European club ranking in terms of Twitter followers ahead of Arsenal, Manchester United and Chelsea in third, fourth and fifth place respectively.
Real have 29.8 million followers while Barca have 28.5 million. That is more than three times that of nearest rivals Arsenal, who lead the way for the Premier League clubs with 5.8 million.
Louis van Gaal's Red Devils are not far behind the Gunners with 5.6 million while Chelsea have 5.5 million followers.
The figures are made all the more impressive when measured against the estimated number of active users on Twitter, which stands at 284 million (as of December).
