Cassano reflected on having to undergo surgery for a congenital heart problem in late October and his subsequent, ongoing recovery.
"It was unexpected, but the important thing was to live. I have to wait six months to play again. Meanwhile, I walk, walk, walk. With all the kilometres that I'm doing I'll be arriving in Bari."
Since joining the Rossoneri in January 2011, Cassano has struck up a friendship with fellow striker Zlatan Ibrahimovic.
"He is one of my best friends, even though he puts pressure on me to return. I have a great relationship with him and with everyone at Milan.
"It is strange that I have a beautiful relationship with everyone, but it's true."
