Chelsea have added youngsters Ato Ampah, Harrison McMahon, Kaiden Wilson, Richard Olise (brother of Michael), Josh Acheampong and Harrison Murray-Campbell to their Conference League squad to play Astana in Kazakhstan.
Tyrique George, Kiano Dyer, Sam Rak-Sakyi and Shim Mheuka were already included.
Manager Enzo Maresca is due to speak to the media this morning after getting special dispensation to hold the club's news conference at their training ground despite Uefa usually stipulating match previews are done in the country the match is played.
It is part of an effort from Chelsea to manage their workload.
The Chelsea squad face an eight-hour flight, and will play Thursday's tie in a time zone that is five hours ahead and at temperatures that are forecasted to be as low as minus 11.
