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...
7. CM/RWB - Dallas
Unclear whether Bielsa will utilise him in the middle or in defence. He adds energy in midfield but may be required for his work rate further back. Either way, has been brilliant this term.
8. AM - Rodrigo
Returned to the bench at West Ham after injury. Without Klich or Roberts in this team a lot of the creativity would land on the Spain international's shoulders.
9. LW - Costa
Has been Bielsa's preferred choice over Jack Harrison in recent weeks. Needs a performance to keep his place, you'd think.
10. RW - Raphinha
When he's on it he looks unstoppable. Will need to be in ruthless form to help Leeds against the Blues.
11. ST - Bamford
Scored in the reverse fixture against his former club. Had a difficult game at West Ham and will be looking to put it right.
