The Whites entertain Jurgen Klopp's Reds at Elland Road on Monday night, having secured the unlikeliest of wins over Manchester City last weekend.
Marcelo Bielsa's men travelled to face Pep Guardiola's champions-elect as underdogs but left the Etihad stadium with all three points in stunning fashion to leave their hosts shocked - who had won 26 games out of 27 matches across all competitions heading into the clash.
Leeds claimed a dramatic stoppage time 2-1 victory through utility man Stuart Dallas, who bagged his second of the encounter with a low finish past goalkeeper Ederson after a lung-busting run forward.

United's triumph was made all the greater following the first half dismissal of club captain Liam Cooper thanks to VAR intervention following a high follow-through on City forward Gabriel Jesus.
The Whites now face another stern test with the visit of Liverpool to West Yorkshire for Monday Night Football - having hauled themselves into 10th place in the standings during their first campaign in England's top division for 16 years.
Klopp's men have seen the Premier League crown slip from their grasp this term after a disappointing campaign by the Anfield club's recent standards under their German head coach.
The Reds will also end the season trophyless following their Champions League quarter-final exit to Real Madrid on Merseyside in midweek.
Phillips, though, is still wary of the threat the visitors pose even if they have endured up and down form recent months, and believes Leeds won't take their foot off the gas despite an impressive win over the Pennines.
“There’s still a lot of work to be done and a big job to be done,” Phillips revealed.
“The high is still there from the Man City game and we know Liverpool haven’t been doing great, but they have started picking up a little bit of form, so it will be a good game.
"We are very excited and if it is anything like the first game of the season it will be one I’ll be very happy to be involved in.
“We’re not going to change the way we play and I don’t think Liverpool will change the way that they play.
“It will be exciting, it will be a good game, hopefully we can go one better and try to beat them this time."
Asked about how he looked back on the victory against Manchester City after having a few days to reflect, he added: "It’s been a very busy period for myself and us here in Leeds. The win at the weekend topped it off, it was a great result for us in a very difficult situation.
“It just goes to show how good of a team we are and when we work together, how well we can play.
“Just the manner of us having 10 men, then playing behind the ball for almost all the game and beating them in that manner was an amazing feeling, we just wish there were fans there.
“After the sending off, it made everyone spur up and say we have to do this for the rest of the game.
“Run as much as we can, help each other as much as we can, we did that and then Stuey [Stuart Dallas] popped up in the 91st minute with the winner."
