Chelsea have asked their international players to return to the United Kingdom by Sunday, according to multiple reports.
The Premier League club are stepping up their preparations for the possible resumption of matches.
The best scenario would see games start on June 8, likely behind closed doors.
Christian Pulisic, Emerson and Willian were allowed to return to their respective homelands to isolate during the coronavirus pandemic.
The league is hoping for clubs to return to full training by May 18, which would allow the three players to quarantine for 14 days before joining their teammates.
