Marcelo Bielsa has some decisions to make in his starting line-up ahead of a top flight clash with the Blades.
Liam Cooper has returned from illness while Spanish duo Rodrigo and Pablo Hernandez are both available after injury but are lacking match sharpness.
Mateusz Klich's inclusion is still being decided after the Poland international contracted Covid-19 while away with his country on international duty.
Leeds also have a number of first team stars returning from a busy spell of action over the past 10 days or so with their respective countries.
The Whites boss finally has a positive selection headache for the clash.
Paul Heckingbottom usually opts for two up front following his appointment as interim manager and Leeds will select a back three to take on a two-man attack if it is the case once again.
Here's how the Yorkshire Evening Post would line-up against the Blades, in a 3-3-1-3 formation that is interchangeable if required:
1. Meslier - GK
Bielsa's number one. Has been away with France Under-21s but didn't see any match action.
2. Llorente - CB
Just the 45 minutes of game time with Spain over the break. Should keep him sharp enough to start.
3. Cooper - CB
United's skipper and usually starts if available. Has just returned from illness but has been back in training for two weeks now. Would replace Alioski in the only change from Fulham.
4. Struijk - CB
Has done enough to warrant inclusion for the moment. Would mean Robin Koch remains on the bench but Struijk's form has been deserving of a spot in the side.
5. Ayling - RWB
Always much more of a threat in his natural position on the right. Loves to get forward and create danger.
6. Phillips - CDM
Fresh from three games for England in 10 days, which have done his Euros chances the world of good. Always starts when fit.
