The Whites are waiting on top scorer and leading striker Patrick Bamford ahead of kick-off at Craven Cottage, who picked up a hip injury against Chelsea last time out.
Bielsa, though, was bullish about his chances of starting the game against Scott Parker's men.
Rodrigo has picked up a muscle problem and is doubtful for the trip to the capital but defender Robin Koch is available once again after picking up minutes with the club's Under-23s side this week.
Pablo Hernandez could return to the squad while Leeds skipper Liam Cooper remains out through illness and Leif Davis also has minor knock - Adam Forshaw (hip) is the only long-term absentee.
Here, the Yorkshire Evening Post pick our line-up for the clash with the Cottagers under the London lights:
1. Meslier - GK
Leeds United's number one. Had a strong showing against Chelsea, did everything he was required to do to keep a clean sheet.
2. Ayling - RWB
Has taken impressively to the Premier League this term. Offers more here, in his natural position, but is a good deputy to have if needed in central defence.
3. Llorente - CB
Finally getting a run of games under his belt after injury problems. Likes a pass, and was solid alongside Struijk last time out.
4. Struijk - CB
It's between Pascal Struijk and Illan Meslier for Leeds United's breakout star in the Premier League. Has taken everything in his stride - looks at home in defence.
5. Alioski - LWB
Had a tough time dealing with Christian Pulisic against Chelsea, which halted his forward progress. Certainly adds to attack when selected.
6. Phillips - CDM
The key cog in Bielsa's machine. A confident display in front of the back four last time out, which provided a defensive platform for Leeds.
