Cardiff owner Vincent Tan has criticised Wigan chairman Dave Whelan and the club's new manager Malky Mackay, telling the BBC: "This is a racist chairman hiring a racist manager."
Malaysian businessman Tan reacted angrily to Whelan's comments about Jewish and Chinese people in a newspaper interview with The Guardian in which he was defending his decision to hire former Cardiff boss Mackay.
Whelan has since apologised for his comments, though the Football Association says it will treat its investigation into Whelan's comments "as a priority," and has written to the 77-year-old giving him three days to respond.
Tan told the BBC he hopes that the FA "considers carefully" the cases of Mackay and Whelan, saying: "I think [Whelan] insulted the dignity of all Jewish people. I think he insulted the dignity of Chinese.
"This is a racist chairman hiring a racist manager. I hope that stops at two racists in Wigan, not snowballing to 2,000 or 20,000 racists in Wigan."

Tan also believes Whelan was wrong to have hired Mackay as the Latics' manager before the FA had completed their investigation of the Scot's comments.
Mackay, who has also denied being racist, is himself the subject of an FA investigation for sending allegedly racist text messages to Iain Moody, his former head of recruitment at Cardiff. He was sacked by the Welsh club earlier this year.
"I think the world is watching what the FA will do," Tan added. "Will it be a regulator on football matters with teeth or a toothless regulator?"
