Frank Lampard and Mikel Arteta will have some important decisions to make ahead of Chelsea and Arsenal's Premier League clash tonight.
Chelsea will hand Reece James a late fitness test ahead after the 20-year-old full-back suffered a knee problem in Saturday's 1-0 loss at Newcastle.
Fellow full-back Marcos Alonso is fit again after a thigh issue and will be in the squad.
As for Arsenal, Arteta will once again be without suspended captain Pierre-Emerick Aubameyang for the short trip across London.
The striker will serve the second of a three-match ban for his sending-off at Crystal Palace, with head coach Mikel Arteta waiting to see if defender Sokratis Papastathopoulos recovers from illness in time to be involved.
Reiss Nelson (hamstring), Sead Kolasinac (thigh), Kieran Tierney (shoulder) and Calum Chambers (knee) are all definite absentees.
