Mackay's position looks increasingly precarious after the Scot was given an ultimatum by Tan to resign or face being sacked.

Mackay failed to turn up for his Friday morning press conference ahead of Saturday's trip to Liverpool, although he has travelled to Merseyside for the Premier League fixture at Anfield.

Tan has already made himself unpopular with Cardiff fans by changing the colour of the club's home kit from its traditional blue to red, as well as hinting he would be prepared to change the club's name in the future.

His decision to dismiss Mackay's head of recruitment Iain Moody in October and replace him with Alisher Apsalyamov caused further consternation, and should Mackay follow his old friend out the door, Cardiff City Supporters' Trust spokesman Phillip Nifield expects fans to make their displeasure known.

"If Malky Mackay is sacked I would imagine it is inevitable that the fans will make their voices heard," Nifield said on Friday.

"I would be astonished if that is not the case.

"I am sure there will be a few banners and chants in support of Malky and against the owner at Anfield, and I am sure there will be more of the same for the home game against Southampton on Boxing Day and it may not be pretty.

"It is tough enough trying to survive in the Premier League and there are concerns those efforts are being undermined by the owner."
