The midfielder explained that he will not sign a new deal if he is going to be sitting on the bench every week, but admitted that the ageing Rossoneri need freshening up
The former Italy international is out of contract this summer and is scheduled to sit down and speak with Rossoneri CEO Adriano Galliani about a new deal in the coming days.
However, Gattuso, who missed most of this season with career-threatening eye problems, has explained that unless he is given assurances over his involvement in the first team, he will have no issue walking away from the game.
"I will speak with Galliani about my future," the midfielder told reporters on Monday. "If I'm not playing, then I'll stay at home with my children and be a father.
"The important thing is that I get to play, to feel that I'm alive. The contents of the contract aren't important."
While the 34-year-old still feels that he has plenty to offer Milan, he admits that the team is in need of freshening up.
"The squad is a bit old, and we need to do something about it," the former Rangers man conceded.
Meanwhile, Gattuso paid tribute to Juventus after the Bianconeri took advantage of Milan's derby defeat to Inter on Sunday to clinch the title with a 2-0 win over Cagliari.
"Congratulations to Juve; they deserved it," the World Cup winner admitted. "But we could have done more and not lost so many matches."
Gattuso, who was capped 73 times by Italy, arrived at San Siro from Salernitana in 1999.
