Antonio Cassano will make his debut for Milan against Fabio Cannavaro's Al-Ahli side in Abu Dhabi.
The 28-year-old Italy international, who is currently on holiday in London, will fly out with Milan on December 27 to attend their annual winter training camp in Dubai.
La Gazzetta dello Sport understands his signing will become official on January 3.
However, he is likely to make his debut a day before that date in a friendly against Al-Ahli.
Cannavaro joined the Dubai-based outfit in the summer after Juventus agreed not to offer him a year extension on a rolling contract.
It's understood that Milan boss Massimiliano Allegri will look to get Cassano fit again simply by playing him, just like he did with Robinho earlier this season.
Cassano is expected to return to Italy today and spend Christmas back in Bari before hooking up with his new teammates.
