Chelsea have reportedly said they will demand four players from Real Madrid if Los Blancos are to sign right-back Reece James.
Since breaking into the Blues' first team in the 2019-20 season, the England international has attracted interest from across Europe, with Real Madrid said to be keen to bring him in as a long-term replacement for Dani Carvajal.
The Stamford Bridge outfit are unwilling to let the 21-year-old go for a low price though, with Thomas Tuchel reportedly telling Los Blancos that he will demand four players as part of the potential deal.
According to Daily Express, centre-back Eder Militao, left-back Ferland Mendy, midfielder Marco Asensio and winger Vinicius Junior have all been mentioned to the Madrid side as crucial parts if they are to secure the English full-back's signature.
Asensio has been linked with a move away from the Santiago Bernabeu over the summer, while Vinicius's spot in the side is said to be in jeopardy if Los Blancos complete their planned move for Kylian Mbappe next year.
At the age of 21, James has already amassed 89 appearances for his boyhood club, having played in every knockout game of last season's Champions League campaign as the Blues went on to secure the trophy.
