Bakaye Traoré is shocked by his move to AC Milan.
The midfielder joins Milan on a Bosman from Nancy.
"I am very proud to become part of one of the biggest clubs in the world," he told the official Nancy website.
"I know they believe in me at Milan, as they tried to sign me several times. Now I am ready to fight for my space in the side.
"It was strange to hear Milan made an approach, as I didn't expect them to show an interest in me. I thought you had to play in the Champions League to attract the attention of a club at this level."
