Charly Musonda and Kenedy were among the players who took part in Chelsea’s training session at Stamford Bridge on Wednesday.
Musonda has returned to Antonio Conte’s side after his loan spell with Real Betis was cut short earlier this month.
The 20-year-old spent the second half of last season on loan with the Spanish club and made an instant impact in La Liga.
Betis managed to extend the Belgian’s spell for the entire duration of this campaign but the midfielder has been restricted to just eight appearances due to injury.
Earlier this month, Musonda returned to Stamford Bridge for an assessment on a knee problem but has since trained with Chelsea’s development squad.
Kenedy, meanwhile, is training with Conte’s first-team squad after his loan at Watford was ended early.
The 20-year-old, who was signed in a £6.3 million deal from Fluminense in June 2015, has played just 16 minutes for Watford in the Premier League this season.
Last week, Watford boss Walter Mazzarri confirmed that Kennedy had been sent back to Chelsea.
‘He was a player we never had time to evaluate because he was injured the whole time,’ he said.
