The Serie A football club is owned by Fininvest, the family holding of former Italian prime minister Silvio Berlusconi.
The source said a meeting between Fininvest and Bee scheduled in the coming days was still set to happen.
"It looks like Bee is coming to Milan. It cannot be ruled out that he may ask for a delay, a postponement of a few weeks to close (the deal)," the source said.
A second source added that Bee was already on his way to Milan.
