Mackay is expected to meet with Tan tomorrow to thrash out their differences.
Asked if he felt the stand-off will affect Cardiff's hopes of staying in the Premier League, he said: "Absolutely. You can't have your dirty linen washed in public every week of the year without it affecting the club.
"That won't happen immediately because it's my job to make sure I protect them (the players).
"They are a great group of people who want to make sure we stay in Premier League football, without a doubt.
"But I am not naive enough to think they don't read newspapers or watch television and think 'what on earth is going on?'."
