Spanish soccer giant Real Madrid claimed Friday world-beating revenue for the sports world in 2010-11, with sales shooting up 8.6 percent to €480.2 million ($663 million).

"It is the biggest sum of any sporting institution in the world," the club said in a statement.

Net profit surged 31.7 percent to €31.6 million in the year to June 30.

The club said it also managed to trim its heavy debt load. Net debt fell 30.6 percent in the year but was still high at €169.7 million.

Real Madrid raked in money from the stadium, television rights, marketing, membership fees and sales of players.

But the huge sums that Madrid and archrival Barcelona claw in from the sale of TV rights has sparked a backlash from other less fortunate clubs in the Spanish league.

The league leaders receive about €140 million a year each from the media deal, while small clubs such as Levante, Malaga or Real Sociedad get just €12 million.
