They were bought by the Chinese-backed Rossoneri Sport Investment Lux company in April and the new owners have shown their ambition with heavy investment in the squad this summer.
Silva firmly established himself as one of the Europe's most exciting young players with 21 goals in 44 first-team appearances last term and has already scored seven times for Portugal in only eight appearances.
And they immediately signalled their intent by bringing in a Silva for a club record fee.
AC Milan continued their summer splurge with arguably the signing of the window so far by sealing the transfer of Andre Silva, and the player who's being tipped for greatness has responded to Cristiano Ronaldo's statement.
It's important that expectations remain tailored to what's actually realistic. Silva has a physical presence in the final third and his strength allows him to hold the ball up well. Moreover, spending time with the iconic striker on the worldwide scene, learning from his experience, will only be beneficial to Silva's development in Milan.
"I'm very happy to have joined such a prestigious club with such a great history", Silva said.
"I thank the people at Real Madrid, the city of Madrid, my colleagues and everyone who helped me get to this point", he told Marca.
He is due to link up with the Portugal national team on Monday night in preparation for the Confederations Cup with Milan therefore unlikely to waste any time in confirming his arrival, if he passes a medical.
