The Belgian striker made a huge impact on the Reds side after coming on as a substitute in the last ten minutes at Anfield.
Origi showed flashes of brilliance, making an energetic run on the left wing past Lucas Digne, before hitting a post and then finally capitalising on Jordan Pickford's error in stoppage time.
The 23-year-old is set to replace Sadio Mane in the starting eleven after the Senegal international suffered a cut on his foot on Sunday.
The manager is also set to rotate some of his key players, according to King.
Alberto Moreno is "likely" to replace Andy Robertson - who suffered a dead leg against the Blues. Meanwhile, Joel Matip, Dejan Lovren, Naby Keita and Daniel Sturridge are also being considered ahead of the game.
Speaking at his pre-match press conference, Klopp praised Origi's impact at the weekend: “It was such an important thing and so nice.
“That’s football as well, sometimes things change in a second in the wrong direction, and sometimes in the right direction.
“He played for about 10 minutes and had three really good situations—the turn and run on the right-hand side with a good cross for Daniel [Sturridge], then the shot that hit the crossbar and the goal.
“He deserved it, so it’s a really nice story.”
