Chelsea are reportedly looking to sell either Marcos Alonso or Emerson Palmieri 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.
According to Goal, 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.
Emerson is yet to feature in the Premier League under Tuchel and has made just two brief substitute appearances in the Champions League.
However, one of those came against Atletico Madrid - with the left back scoring a breakaway goal in the final minute to confirm Chelsea's place in the quarter-finals.
That is the only goal the 26-year-old has scored this season while Chilwell has netted three times and has five assists in all competitions. Alonso also found the net once.
Both Alonso and Emerson are out of contract in 2022 but Chelsea have the option to extend for another year, giving the club extra leverage in any negotiations.
Emerson has had previous interest from Juventus and Inter Milan. The defender was signed for the Blues by current Inter boss Antonio Conte while Juve are said to remain interested after failing to land him in January.
The Blues spent over £253 million on new players last summer and are looking to add to their squad once again.
Signing a striker is Tuchel's priority with Erling Haaland and Romelu Lukaku both on the club's radar. However, Lukaku has insisted he is not looking to leave Inter Milan.
The club will listen to offers in the region of £40m for top scorer Tammy Abraham to raise more funds.
Olivier Giroud is likely to depart on a free transfer with his contract set to expire at the end of the season.
