Nesta was plagued by injuries in his final years against Milan, but he still achieved the only double of his career against Chievo, and in the 2000-2001 season AC Milan once again dominated Serie A, winning the Serie A two rounds earlier.
On 6 August 2011, Nesta helped AC Milan win the Italian Super Cup in a 2–1 victory over Inter Milan at the National Stadium in Beijing, leaving the memory of the last European title in Beijing.
Nesta AC Milan closed the curtain battle
In the summer of 2012, Nesta said goodbye to AC Milan, who had been with him for ten years, and he took off the No. 13 red and black shirt he had worn for ten years, Nesta joined Major League Soccer League Montreal Impact Football Club as a free agent, becoming the brightest superstar there, a year later he finally bowed to time and chose to retire, but after only nearly a year, when people thought it was impossible to see Nesta running on the pitch, he miraculously announced his comeback. Joined The Titans Chennai in the Indian Premier League, but after only three games, Nesta finally compromised with his body and announced his retirement for the second time.
The once spirited Nesta guarded the cities of Rome and Milan for nine years, nine years of blue eagles, and ten years of red and black. Maybe we will never see a man who can play defense so gracefully as Nesta, goodbye, the eternal guardian of elegance - Alessandro Nesta.
