Head coach Marcelo Bielsa has already confirmed that playmaker Pablo Hernandez will miss another two weeks with his groin injury and the YEP's Lee Sobot takes a look at a predicted Whites starting XI for the high noon showdown at Bramall Lane.

No goalkeeper will be happy conceding seven goals in two games and Meslier might have done better with two of the three against Fulham but learning all the time and looks sure to start in goal. Photo by Oli Scarff - Pool/Getty Images.

4. Robin Koch (CB)
The German international summer recruit has conceded two penalties in his first two games but solid work has prevented other goals and looks set to start with Diego Llorente probably beginning from the bench. Photo by Shaun Botterill/Getty Images.
5. Stuart Dallas (LB)
Play him where you like. But Leeds United's Mr Versatile has made the left back slot his own and all set to continue there. Photo by Laurence Griffiths/Getty Images
6. Kalvin Phillips (CDM)
Leeds United's new England international and the Yorkshire Pirlo will clearly be in the holding midfield role unless Bielsa happens to opt for a change of system but no signs of changing the set up at present. Photo by Oli Scarff - Pool/Getty Images
