Bayern Munich chief Uli Hoeness admits he remains upset with the way Spanish clubs are allowed to get away with their massive debts.

Bayern face Real Madrid in the Champions League semifinals with Hoeness still furious over the difference in how the respective teams treat their finances.

"I have great respect for that club, its name, its tradition. The only thing I dislike is that it is a club that has great athletic success but will not pay their debts by itself. That's a problem," said Hoeness.

"I reacted to the news of the €750 million of Treasury debt of Spanish clubs. I cannot understand this! Germany is giving people a lot of money to survive and then this happens.

"I think you have to treat everyone equally. And to me it seems incredible that in Spain three years ago you paid a maximum tax for the players of 25%. It was a great advantage for Spanish clubs. In Germany we pay 45%."
