The 36-year-old's future is up in the air with his current deal with the Rossoneri outfit ending next month.
He does not want to call time on his career, though, telling Italian TV station LA 7: "I have taken a week to decide. I don't want to retire.
"I will play for another two or three years and I don't exclude anything, not even the possibility to remain at Milan."
Seedorf, a four-time UEFA Champions League winner, scored two goals in 18 league appearances for Milan this season.
The Dutchman joined the Serie A giants in 2002 from city rivals Inter Milan.
