Chelsea could welcome the prospect of swapping Emerson for Juventus defender Alex Sandro this summer.
The Blues have operated with the wing-back system since the arrival of Thomas Tuchel as the manager in January.
According to Calciomercato, Juventus have a long-term interest in Emerson, and they will propose a swap deal involving Sandro.
Sandro has two year remaining on his contract unlike Emerson (June 2021), but the Bianconeri want to sell him to reduce their wage bill.
The Blues were first linked with Sandro more than four years ago, and they have continued to be associated with him.
The Brazilian is more defensively organised when compared to Alonso, and his arrival may pave the way for the latter’s exit.
Tuchel is a huge admirer of the former Porto man. He tried to sign him for Paris Saint-Germain in the summer of 2018.
