Chelsea square off against Crystal Palace on Saturday afternoon looking to end a two-match winless streak in the Premier League.
The Blues picked up just one point from games against Liverpool and West Bromwich Albion, while their latest setback came courtesy of a penalty-shootout defeat to Tottenham Hotspur in the EFL Cup.
While Frank Lampard's selection dilemmas are gradually easing by the week, the Chelsea boss still has a number of concerns in the days leading up to the contest with Palace.
Here, Sports Mole rounds up Chelsea's latest injury and suspension news ahead of the derby clash at Stamford Bridge.
Status: Out
Type of injury: Knee
Possible return date: Unknown
Gilmour has been sidelined with a knee injury since the summer and is not expected back in contention until November at the earliest.
Status: Major doubt
Type of injury: Knee
Possible return date: October 3 (vs. Crystal Palace)
Lampard has suggested that he is not prepared to take any risks on Ziyech, who suffered a knee problem in a pre-season friendly against Brighton & Hove Albion. If the playmaker is not available at the weekend, he should be in line to make his debut after the international break.
Status: Major doubt
Type of injury: Hamstring
Possible return date: October 3 (vs. Crystal Palace)
When commenting on their recovery periods, Lampard mentioned that Pulisic was following a similar path to Ziyech after a hamstring injury. While one of the two may feature in the squad at the weekend, it appears unlikely that both will be included on the substitutes' bench.
CHELSEA'S SUSPENSION LIST
Chelsea do not have any suspension issues ahead of this encounter.
