Bee Taechaubol is expected in Milan today.
The Thai businessman has left Bangkok and is in mid-flight to Italy.
Bee is due to meet with AC Milan president Silvio Berlusconi so to discuss the future of their agreement.
The consortium that Bee fronts has agreed a €485 million purchase of 48 per cent of the club. But as yet, the deal is yet to go through.
There's concerns that Bee's group do not have the funds to complete the deal.
