Manchester City are demanding an apology from Bayern Munich president Uli Hoeness after his latest spending power jibes.
Hoeness made extraordinary claims that owner Sheikh Mansour pays for transfers by ramping up the price of oil.
A City source told the Sunday Mirror: “It was the remark of a smug, arrogant egotist.
“We are also concerned that there may be a racist element to what Hoeness has claimed."
It's reported the matter has been placed in the hands of City's lawyers.
