Marcelo Bielsa has decisions to make ahead of the visit of the Blues in the top flight this weekend.
With the Argentine's treatment room woes easing slightly, Leeds now have a number of players back and in contention for his Whites matchday squad in LS11.
Kalvin Phillips returned to his starting line-up at West Ham while Rodrigo and Gaetano Berardi were handed a place on the bench.
Pascal Struijk (knock) and Pablo Hernandez (muscle) will miss out this weekend as will long-term absentees Robin Koch (knee) and Adam Forshaw (hip).
Jamie Shackleton, though, is in contention for inclusion after being sidelined since the defeat to Wolves last month.
Chelsea have varied formations under Thomas Tuchel since his arrival, which could see Leeds line-up in either a 4-1-4-1 or a 3-3-1-3 formation depending on how many attackers are chosen.
Here, the YEP select our starting XI that could be deployed in either tactical set-up against this weekend's visitors - and it includes a few changes...
2. RWB/CB - Ayling
Could play as part of a back three or in his natural position on the right. Certainly adds to the attack when he plays in the latter.
3. CB - Llorente
Has a tricky night at West Ham but it's good to see him finally get a run in the side.
4. CB - Cooper
Bielsa's skipper and usually starts when fit. Has been in impressive form of late.
5. LWB - Alioski
Added something from the bench against the Hammers on Monday. Did struggle at Chelsea in the reverse fixture but could be called upon once again.
6. CDM - Phillips
The key cog in the machine. Kalvin is going to have his hands full with the Chelsea attack.
