Mackay is reportedly livid with owner Tan for dismissing his right hand man Moody, who was the head of recruitment at City, and replaced him with friend of the family Alisher Apsalyamov.
Apsalyamov was on work experience at the Cardiff City stadium just two months ago and now has key role at the club, leaving Mackay to ponder his future.
Mackay will attend a board meeting tomorrow to discuss the weeks’ events but unsurprisingly Tan will not be around.
“I have every faith in Malky and his team to lead us through the challenges of the Premier League,” Tan said on the clubs official site.
“I have supported him in the past and will do so in the future for many years to come.
“I would say to all Cardiff City fans and everyone connected to the club, let us look forward to the future and remain united in our support of the team.”
