Frank Lampard has said new signings Timo Werner and Hakim Ziyech could train away from the Chelsea first-team squad to ensure they peak for the start of next season.
Ziyech and Werner officially join on Wednesday from Ajax and RB Leipzig respectively but are ineligible for the rest of the campaign due to registration rules.
However, the pair can immediately begin practicing with their new teammates and Werner declined to take part in Leipzig's Champions League quarterfinal scheduled for August to start his life in London as soon as possible.
It is understood various logistical details have to be determined, including adhering to the government guideline requiring new arrivals to the United Kingdom having to self-isolate for 14 days upon arrival due to the coronavirus pandemic.
That guideline is expected to be relaxed for arrivals from the European Union from Monday while the first-team squad are tested for COVID-19 twice a week, meaning it is theoretically possible both players could be cleared sooner to train.
Asked about his plans for Ziyech and Werner, Lampard said: "I'm in the process of arranging that now. They do become our players. Hakim hasn't played for a while and Timo finished at the weekend.
