The club's owner said that "the main person responsible for relegation is Malky Mackay, the hero of fans."
Cardiff City owner Vincent Tan has launched a fierce attack on former manager Malky Mackay, blaming him for the club's Premier League relegation.
Tan removed Mackay from his post in December 2013, accusing him and recruitment chief Iain Moody of overspending by 15 million pounds.
Those accusations have always been denied by the pair, but they both issued unreserved apologies to the club's Malaysian chief last week, with Mackay opting to drop legal proceedings against Cardiff.
And, despite Cardiff claiming just 12 points under replacement Ole Gunnar Solskjaer, Tan has laid the blame for the club's return to the Championship at the feet of Mackay.
"The main person responsible for relegation is Malky Mackay, the hero of fans," Tan told Wales Online. "They should ask why he apologizes? They should find out from him. Legally, I'm not supposed to say. I wish I could say, but I can't. Ask him why he apologizes.
"His friends supported him to be a big hero, unfortunately their hero almost killed this club and I was not going to be putting more and more money in."
