At his presentation today, Maignan declared: "I immediately felt this wonderful atmosphere, I was well received, there is professionalism, we must all contribute to doing well for this historic club.
"A great job has always been done at Milan and Donnarumma has also contributed to the club, he is a great goalkeeper, but I start with my history at Milan. I will work as hard as he did. I have had contact with Dida, he will be able to help me a lot to progress on my personal path.
"When (directors Paolo )Maldini and (Ricky) Massara contacted me it was exciting, I was pleased. I immediately confirmed that I was ready to face the adventure with Milan.
"Donnarumma made his story at Milan, it was right to wait for the adventure with Milan to end. But everything went well and now I'm here."
Maignan also revealed: "I was also contacted by Roma but the negotiations with Milan had already started and then I closed with the Rossoneri."
