Moses will, however, hope to be part of the squad when Chelsea kick-start their pre-season with a friendly against Perth Glory on July 23 before entering the International Champions Cup at the end of the month.
Amid the speculation regarding Antonio Conte's future at Chelsea, the Italian boss has arrived at the club for the start of the pre-season.
Stars such as Pedro, Cesc Fabregas, Marcos Alonso and Alvaro Morata who were not involved in the World Cup with their global sides reported for duty over the weekend.
Conte is renowned for his highly vigorous approach to approach to preseason and several Chelsea players have publicly admitted to struggling with his gruelling summer programmes, though weeks of double sessions at Cobham provided the foundation for the club's surprise run to the Premier League title in the 2016-17 campaign.
So with Chelsea having arranged pre-season preparations to start today, not many would have been expecting Antonio Conte to still be in charge.
Conte is refusing to walk away from his job unless Chelsea agree to pay up the final year of his deal - believed to be worth in the region of £9 million - in full and compensate his backroom staff.
Here is a video that the club have released of the players being put through their paces.
Cesc Fabregas posted a picture with David Luiz, Emerson Palmieri and Davide Zappacosta in the physio room, as the players went through medical tests after the session.
