Chelsea boss Thomas Tuchel has named his squad to face Zenit in the Champions League opener.
Tuchel has made five changes for Chelsea but still has a really strong side.
Chalobah, Thiago Silva, Hudson-Odoi, Saul, and Havertz drop out, replaced by Reece James, Cesar Azpilicueta, Andreas Christensen, Jorginho, and Mason Mount.
Romelu Lukaku starts, but Timo Werner is on the bench alongside plenty of others chomping at the bit to get some minutes, none more so than Ben Chilwell.
Chelsea XI: Mendy, James, Azpilicueta, Christensen, Rudiger, Alonso, Kovacic, Jorginho, Mount, Ziyech, Lukaku
Subs: Kepa, Bergstrom, Silva, Werner, Loftus-Cheek, Chalobah, Saul Niguez, Barkley, Hudson-Odoi, Chilwell, Havertz, Sarr
Zenit XI: Kritsyuk, Sutormin, Chistiakov, Rakitskyy, Douglas Santos, Malcom, Wendel, Barrios, Kuzyaev, Claudinho, Azmoun
Subs: Kerzhakov, Odoevski, Krugovoi, Mostovoy, Erokhin, Dzyuba, Kravstov, Khotulev
