Results have picked up for Everton since that defeat to Leeds a little under two months ago, with the Toffees collecting 17 points from the 27 on offer since then.
Saturday's 2-0 home loss to Newcastle United may have killed off the Toffees' momentum, but they still find themselves only six points behind the top four with two games in hand.
That defeat to an out-of-form Newcastle came on home soil, though away from Goodison Park they have won four of their last five in the league, including each of the last three.
Not since December 1985 have the Merseyside outfit won four top-flight away games in a row, but Elland Road is not a happy hunting ground for Everton.
Indeed, the Toffees have won only one of their last 37 top-flight away games against United - a 1-0 victory in November 2002 thanks to a Wayne Rooney goal.
Leeds enter this contest full of confidence, too, having won back-to-back league matches against Newcastle and high-flying Leicester City.
However, while Everton have looked impressive on their travels, Leeds have won just two of their last eight at home, most recently losing 1-0 to Brighton & Hove Albion.
Should he achieve that, Bielsa's men could move into the top half of the table. Victory for Everton, meanwhile, and Champions League football next term will remain a realistic aim.

Patrick Bamford sustained a dead leg in the 3-1 win at Leicester, a game in which he scored one and set up two more, but he expects to be fit and available for Wednesday's game.
Despite his place in the side being called into question, Ancelotti kept faith in goalkeeper Jordan Pickford against Newcastle and that should remain the case here.
Leeds United possible starting lineup:
Meslier; Ayling, Struijk, Cooper, Alioski; Phillips; Costa, Dallas, Klich, Harrison; Bamford
Everton possible starting lineup:
Pickford; Holgate, Mina, Keane, Godfrey; Doucoure, Gomes; Richarlison, Rodriguez, Digne; Calvert-Lewin
We say: Leeds United 1-1 Everton
Everton may be better off than Leeds in terms of points, but the home side enter this game in better form thanks to back-to-back victories.
Of the 45 teams the Toffees have faced at least 10 times away from home in their top-flight history, their lowest win rate on the road is against Leeds.
However, Ancelotti's men have looked good on their travels and we can see them taking at least a point from this latest trip to Elland Road.
