I heard that Sven Goran Eriksson is also in the mix. Apparently Tan has been in discussions about him taking over from Mackay.
Eriksson has been on a downward spiral since his time as England manager and is now in charge of some obscure Chinese team Guangzhou R&F. If he gets the job, it will show him as the true 'mercenary' that he is. I believe he's not managed a club for more than a year since in England and I've felt he was always over-rated and only in it for the $$$. Post England, his managerial record is pathetic.
Perhaps if Eriksson gets the nod, it was be retribution time for Tan. They both deserve each other... two clueless men who think they know something about football.
