Boss Jesse Marsch has a particularly major decision to make at right back as Luke Ayling's season is now over following his straight-red card in Sunday's 2-1 defeat at Arsenal.
The defender must now serve a three-match ban at a time when Leeds are already without another key right back option in Stuart Dallas who is facing a lengthy spell on the sidelines with a femoral fracture.
Another right back option, Cody Drameh, has returned to Thorp Arch after his loan spell at Cardiff City but the 20-year-old is not eligible to feature in United's run-in.
Marsch still has other injuries to contend with as Adam Forshaw, Tyler Roberts and Crysencio Summerville are all out for the season.
Captain Liam Cooper also missed Sunday's defeat at the Emirates due to a knee issue and it remains to be seen how quickly Whites no 9 Patrick Bamford can return from his foot injury.
Leeds will be relegated if they fail to pick up another point from their final three games bar a miraculous goal difference swing and this is how we think the Whites will line up against Thomas Tuchel's third-placed Blues.
7. CDM - Robin Koch
It would be no surprise to see Koch at right back and Mateusz Klich partnered Phillips in midfield at Arsenal so it could be well same again. Koch, though, is a more defensive option there which Marsch might opt for given the threat of the Blues. Lewis Bate needs thinking about too.
8. RW - Raphinha
Raphinha at right-wing back and on long throws. Who would have thought it? If Marsch goes for a back three/five then the Brazilian might well be asked to play deeper but Leeds need goals and Raphinha's magic is needed in the final third.
9. LW - Jack Harrison
There's always been the choice of Harrison or Dan James for left wing/left midfield but James was deployed in another different role at Arsenal and it might well be same again against Chelsea.
10. ACM - Dan James
James lined up in the no 10 role as Joe Gelhardt finally got another start upfront against Arsenal but it all went to pot after Ayling's red card led to Gelhardt being sacrificed for another defender. This, though, presents another chance to see James and Joffy together.
11. ST - Joe Gelhardt
Gelhardt replaced Rodrigo upfront for still only his third league start against Arsenal but the game was a write-off for the exciting young striker given the early reshuffle. With Bamford still on the way back, Leeds need a spark upfront and Joffy is surely the one to provide it.
