Chelsea will seek to sell Marcos Alonso or Emerson Palmeiri this summer.
Goal says Chelsea are looking to sell either Alonso or Emerson to raise funds for a summer transfer spree.
Ben Chilwell, who joined the Blues for £50million in August, has emerged as Thomas Tuchel's first choice left back with Alonso and Emerson finding themselves on the sidelines for the bigger games.
Chelsea will look to offload one of the two defenders this summer in order to raise money for Tuchel to spend on new players.
Tuchel initially appeared to favour Alonso, bringing the 30-year-old backing into the fold after he had been frozen out by former boss Frank Lampard.
However, Chilwell has started the last four Champions League games including the two semi-final legs with Real Madrid. He also started the crucial Premier League fixture against West Ham.
