The Italian Under-21 international has been in and out of the Milan side this season and he has attracted the interest of Bologna.
The Rossoblu would like to take the former Atalanta star on loan for next season and Milan could be keen to do business.
Milan are keen on signing defender Marcello Castellini from Bologna, who could be willing to exchange the 29-year-old in a swap deal for Donati.
Donati is determined to prove his worth at Giuseppe Meazza and he hopes to be still there next season.
"I did not play many games this season," said Donati. "I think this has not been a good season for me, but I hope to be confirmed for next season".
