Nonetheless, they will demand a record fee for the defender.
It emerged last night that the Blues had struck personal terms with the Brazil international, who is keen to move to London.
And according to Gazzetta dello Sport, the Serie A titleholders, having earlier intimated zero willingness to sell, are now having a rethink.
The Bianconeri are convinced they can rake in a staggering €60 million from Chelsea in order to sell Sandro.
And the Serie A champs have identified Nice left-back Dalbert Henrique as a replacement.
Sandro has made 43 appearances during this season.
