The 37-year-old is currently out of contract having played for Fiorentina last season, and despite offers to continue playing abroad, Ambrosini has admitted his career is likely to come to an end.
"I'm 90 per cent sure that I'll stop playing and work in television," Ambrosini told Il Resto del Cirino.
"I'm sorry that I'm quitting after 20 years, it's been a great career, and I have had a few interesting proposals from teams abroad."
Ambrosini will be best remembered for his 18-year stay at Milan, where he won two Champions League titles and four Scudettos on the way to making over 300 appearances for the club.
The midfielder, who earned 35 senior caps for Italy, says talks are ongoing over his immediate future in broadcasting.
He added: "There have been talks with a few televisions stations, but nothing is definitive yet."
