Following a strong showing at Brentford in midweek - and calls for Kiko Casilla to be dropped - we're expected Bielsa to name an unchanged line-up for the clash with the Robins. Lee Johnson, though, favours a 4-4-2 which means Leeds could be set for a formation change to deal with two strikers. Here's how we believe United may set out in a fluid 3-3-1-3...
7. Mateusz Klich - AM
Phillips' return behind allowed him to get forward more in midweek and he looked back to his best. Ever-present under Bielsa.
8. Pablo Hernandez - AM
In a 3-3-1-3, Hernandez has more of a free role to move about onto the wings and get through the middle. Could be just what he needs to give him a little boost. Leeds need him.
9. Jack Harrisom - LW
Harrison is often left to work the whole of whichever flank he is selected on when Leeds opt for a three man defence. Don't be surprised to see it again.
10. Patrick Bamford - ST
Needs a goal.
11. Helder Costa - RW
Like Harrison will be asked to monitor the whole of his flank should Leeds deploy a three at the back. Could do with a strong showing to quieten the doubters.
