The American named an unchanged line-up when his squad travelled to the south coast to play Southampton last weekend but was forced to make early adjustments as Whites number nine Patrick Bamford began to move awkwardly midway through the first half.
In his press conference on Friday, Marsch claimed a decision on Bamford’s availability was yet to be made but stressed that there was a risk attached to bringing him back to soon as the England international is having trouble finding fitness after a season heavily disrupted by injury.
In addition to Bamford, Marsch is missing Luke Ayling, Liam Cooper, Junior Firpo and long term absentee Stuart Dallas.
This is how we think Leeds will line up against Chelsea at Elland Road on Sunday afternoon:
1. GK - Illan Meslier
First on the teamsheet, the Frenchman is yet to put a foot wrong this season.
2. RB - Rasmus Kristensen
Kristensen drew great excitement from Leeds fans when he signed from RB Salzburg this summer. Whites supporters have seen plenty of his character but his full potential is yet to be realised as the Dane familiarises himself with a new division. His spot is safe until Ayling returns.
3. CB - Diego Llorente
The Spaniard hasn’t been hugely consistent this season, but Marsch is likely to stick to the Koch-Llorente pairing at least until more of his defensive players have returned from injury.
4. CB - Robin Koch
With captain Liam Cooper sidelined with an issue with his achilles and Pascal Struijk required to fill the left-back hole, Koch will take on the centre-back role alongside Diego Llorente. The German proved a strong leader against the Saints.
5. LB - Pascal Struijk
Not performing like a man who’s being played out of position. Cracking start to the campaign for the Dutchman, who will fill in at least until Junior Firpo returns in a couple of weeks.
6. RW - Dan James
Made a case for himself off the bench at Southampton and gave a good showing for the Under 21s in their season opener. Will prove a trusty deputy as Aaronson shuffles into the middle.
