Chelsea are prepared to sell Juan Cuadrado.
Blues manager Antonio Conte is a long-term admirer of the former Fiorentina man.
However, the Colombia midfielder is wanted by Juventus, AC Milan and Atletico Madrid.
Leggo says the Rossoneri are keen to bring him to San Siro, but wouldn't be able to pay the €30m asking price.
They are therefore hoping to lower the transfer fee through intermediary Alessandro Lucci.
