The Whites face a tricky third round tie against League Two opposition this weekend. The FA Cup, though, provides an opportunity for Leeds to give a run out to those pushing for starting places at Elland Road.
Tyler Roberts has been ruled out while club captain Liam Cooper and centre-back Diego Llorente are fit an available once again. The latter is unlikely to be risked and a number of United's Under-23s players - such as Joe Gelhardt and Sam Greenwood - may make the bench.
Here is the line-up we think Bielsa may choose against the Red Devils, with a host of changes to come. Crawley Town often opt for a 4-4-2, meaning Leeds would match up with a 3-3-1-3.

5. RWB - Ayling
No afternoon off for Bill. He may, though, move back into his usual right-back role after a recent spell in the heart of defence. He'll have license to get forward.
6. LWB - Davis
A player Leeds fans need to see more of. Has pace to burn and a chance at left-back would be welcome.
7. CM - Shackleton
Has been impressive in his cameo appearances in the Premier League. An opportunity to show his stuff for a full game.
8. AM - Hernandez
Looking for more minutes in the Premier League but has been kept out by the form of others. Unlocking Crawley may help his chances.
