Ahead of the Premier League's first ever Welsh derby with Swansea City, the Bluebirds' boss has seen his relationship with owner Vincent Tan completely break down.
Mackay is said to have become increasingly disillusioned since the sacking of Head of Recruitment Ian Moody, according to The Mirror.
Mackay's contract does not expire until 2016.
