Super Eagles duo of Victor Moses and Kenneth Omeruo were present in training, as Chelsea began preparations for the 2017/2018 season on Monday.
Omeruo spent last season on loan at Turkish side Alanyaspor, his fourth temporary exit from Chelsea.
The defender joined the first team
at their Cobham training base, for their first full day of pre-season. He is however expected to seal a loan or permanent move away from Stamford Bridge.
Moses, who was part of the squad that won the Premier League title last season, was also out on the pitch after he underwent surgery after the FA Cup.
They joined first-team stars like Gary Cahill, David Luiz, Pedro and Willian, as they were put through their paces.
