The Whites entered last weekend's match off the back of a 1-1 draw at Brentford, and the two positive results have left them second in the table, three points clear of third-placed Fulham.
Bielsa's side are also only four points off leaders West Bromwich Albion, showing that first position is still very much open for the team if they can put together a consistent run of results.
Both Sheffield Wednesday and Wigan Athletic have won at Elland Road since the turn of the year, though, while Millwall scored twice in a 3-2 loss at the end of last month.
The fact that Reading will enter this match off the back of such a strong performance last weekend puts even more pressure on Leeds, who will be desperate to right the wrongs from the 2018-19 campaign.
Reading actually finished third in the Championship at the end of the 2016-17 campaign but have posted 20th in their last two seasons at this level. It has been another inconsistent term for the Royals, although they are 11 points clear of the relegation zone.
The table suggests that the club will not have any relegation fears in the final months of the season, and they are actually only six points off 11th-placed Swansea City on the same number of matches.
Mark Bowen's side will be the underdogs heading into this weekend's contest but as mentioned, recorded a 3-0 victory away to Sheffield Wednesday last weekend. They also only narrowly lost against West Brom on February 12, showing that they can compete against the better sides in the division.
Reading have lost each of their last three Championship matches with Leeds, though, and suffered a 1-0 defeat in the reverse match at the Madejski Stadium back in November.
Leeds Championship form: LWLLDW
Reading Championship form: DLDDLW
Reading form (all competitions): LDWDLW
Kiko Casilla will again keep his spot between the sticks, and it seems likely that the same XI that started the win over Bristol City will take to the field.
Pablo Hernandez is also expected to keep his spot despite recent criticism of the Spaniard's form.
Bowen could opt for the same XI that started the three-goal success over the Owls, where centre-forward George Puscas grabbed his eighth Championship goal of the campaign.
Leeds possible starting lineup:
Casilla; Ayling, White, Cooper, Dallas; Costa, Hernandez, Phillips, Klich, Harrison; Bamford
Reading possible starting lineup:
Rafael; Yiadom, Morrison, Moore, Richards; Swift, Rinomhota; Meite, Olise, Ejaria; Puscas
We say: Leeds 2-0 Reading
Reading have a number of injury problems heading into the match, but Leeds are in fairly good shape at the moment. The Whites have been much better in their last two fixtures after a tough period, and we expect them to pick up another three important points on Saturday afternoon.
