Raheem Sterling, Joao Felix, Axel Disasi and Ben Chilwell have been left out of Chelsea’s 28-man squad for the Fifa Club World Cup.
The quartet cost the Blues about £179m in transfer fees and all ended last season out on loan.
The first edition of the expanded Club World Cup format begins in the United States on Sunday, 15 June (01:00 BST).
Sterling cost £50m when he arrived from Manchester City in 2022, but the 30-year-old England forward spent last season on loan with Arsenal, starting just 13 games and scoring once.
Felix made a permanent move to Chelsea last summer for £45m and scored seven goals from 20 appearances before the Portugal forward, 25, ended the campaign on loan at AC Milan.
The Blues paid £38.5m to sign Axel Disasi from Monaco in 2023 and the 27-year-old France defender played 17 games last term before ending the season on loan with Aston Villa.
Chilwell was a £45m signing in 2020 and, after just one Chelsea game last term, the England left-back, 28, spent the rest of the season with Crystal Palace, being an unused substitute in the Eagles’ FA Cup final win over Manchester City.
Serbia goalkeeper Djordje Petrovic, 25, will not be travelling the US either, after spending last season on loan with Strasbourg.
