The 26-year-old emerged as one of Chelsea's top targets earlier this summer but Antonio Conte was left frustrated by the club's inability to close a deal. That has been a running theme this summer, with Chelsea also missing out on Romelu Lukaku.
The Premier League champions saw a world-record bid turned down by the Italian side earlier this summer and English publication 'The Daily Mail' reports that they have now seen another approach rebuffed.
Sandro has established himself as one of the best attacking-minded left-backs in the world following his move from Porto two years ago and he is considered tailor-made for the wing-back role in Chelsea's 3-4-3 system but Juve are staunchly refusing to sell as they look to build a side capable of winning the Champions League.
