The Blues' possible ascent to the summit could be seen by up to 2,000 fans following the end of England's second lockdown, and Chelsea will be desperate to treat their returning supporters to another victory.
Frank Lampard's side have won seven of their last eight matches across all competitions and are unbeaten in 12 ahead of Leeds' visit.
Here, Sports Mole rounds up Chelsea's latest injury and suspension news ahead of the contest.
Status: Minor doubt
Type of injury: Ankle
Possible return date: December 5 (vs. Leeds)
Ben Chilwell rolled his ankle against Tottenham Hotspur last weekend but recovered in time to be part of the matchday squad in Seville. The England international was an unused sub in that match, but should be fit to return this weekend.
CHELSEA'S SUSPENSION LIST
Chelsea have no players suspended for the visit of Leeds, meaning that Lampard has an entirely full squad to pick from.
