Despite a poor season on the pitch, United's income surged to 518 million euros (USD 599.4 million), from 424 million the previous year, with commercial revenue rising 24 percent and broadcast income 34 percent, Deloitte said on Thursday.

Real topped the rankings for a 10th year, coinciding with the La Liga club's record-extending 10th European crown, with revenue of 550 million euros, up from 519 million.

Bundesliga champions Bayern Munich were third on 488 million, closely followed by Barcelona, who failed to win major silverware for the first time in six years, with 485 million.

United's strong performance is expected to continue thanks to a record seven-year shirt sponsorship deal with General Motors that started this season and a 10-year agreement with Adidas from 2015-16 worth USD 1.14 billion, Deloitte said.

The club had also benefited from a new cycle of Premier League broadcast contracts.

BROADCAST DEALS: Deloitte's latest figures, which exclude player transfer fees, VAT and other sales-related taxes, showed Real's dominance was again partly due to the way broadcast deals are negotiated in La Liga.

Unlike in other major European leagues, which have a system of collective bargaining and shared income, Spanish clubs agree contracts individually.

Real and Barca take about half the total La Liga pot of about 600 million euros between them, meaning they are better able to afford top players.

Real earned 204.2 million euros and Barca 182.1 million in broadcast revenue in 2013-14, compared with 162.3 million for United and Bayern's 107.7 million, Deloitte said.

Atletico Madrid's TV income surged 84 percent to 96.5 million euros thanks to 50 million from UEFA for their run to the Champions League final, which they lost to Real.

Ranked 15th in 2013-14 with total income of 170 million euros, the La Liga champions are the only other Spanish club in the top 20.
