The 41 year-old said: â€śIâ€™ve been saying it for a while now, but this time I really think the moment has come to stop playing football.
â€śI will remain in this sport in another capacity, but at this moment I am not sure whether I want to be behind the scenes or a Coach.â€ť
Milan are struggling to construct a solid defence, but the captain thinks they already have his heir.
â€śIn the future Thiago Silva will do a great job, but I still say that Milan must focus on Alessandro Nesta for the present and immediate future.
â€śI think he will be back stronger than ever. I spoke to him recently and he was fired up, enthusiastic and at last relieved his back problems are improving.
â€śClearly if he returns, which Iâ€™m sure he will, then it is to play at the highest level. Iâ€™m betting on Nesta to take on my mantle. He is a real champion and the best centre-back around.â€ť
