Bayern Munich have hit back at former German FA (DFB) president Dr Theo Zwanziger after he criticised their recent friendly in Saudi Arabia.
The Bundesliga champions followed their winter training camp in Qatar with a stopover to play Al-Hilal.
Suddeutsche Zeitung reported that they earned more than one million euros, with the fee paid by Bayern stakeholders Volkswagen.
Bayern were criticised for failing to address human rights issues in Saudi Arabia by German politicians, football fans and the media.
Zwanziger, a FIFA executive committee member until May, said he was not surprised to find that "commerce beats ethics" and that "when in doubt, the moneybag is closer."
In a written statement last week, Bayern CEO Karl-Heinz Rummenigge stressed that the club "condemns all forms of cruel punishment that are not consistent with human rights" and admitted "it would have been better to clearly address this on the occasion of our match in Saudi Arabia."

And on Friday, Bayern hit out at Zwanziger in a column published on their official website under the name Sabener Sigi, with Sabener referring to the address of the club's training ground.
The column cited several occasions on which Zwanziger had praised Bayern's leadership and suggested he may have had problems remembering them. It asked: "Does the Doctor need a doctor?"
Zwanziger, in Bild, responded by saying Bayern had changed and would never have hit out anonymously in the past.
But Rummenigge defended the column, saying it had been written by an "independent satirist" and that the club had been right to address Zwanziger's criticism.
"It was low down from good Theo. I don't have any contact with Theo -- nobody has in Germany," Bild reported him as saying. "He should ask himself why that's the case."
