The Bluebirds are preparing to make the jump to the Premier League after guaranteeing a top-two finish in the Championship earlier this week and Mackay has paid tribute to the Malaysian businessman for the influence he has had behind the scenes this campaign.
"This season is probably when he's gone hands-on at the club," said Mackay. "In that respect there's been a lot of firsts for him in terms of learning about the game, the football club, the division and life in south Wales.
"A lot of credit has to go to him for adapting to that because he's a very successful businessman in his own part of the world. He's got his finger on the pulse over there.
"For him to come over here and give trust in me and my staff and allow me the chance to bring a group of players together I felt that could be promoted is great."
