The Reds head to London looking to return to winning ways after they squandered a two-goal lead to draw 2-2 against Sunderland at Anfield in the Premier League on Saturday afternoon.
Sturridge was an unused substitute during Liverpool’s draw with the Black Cats on Merseyside, while Coutinho and Origi are now closing in on returns to action.
And speaking at his news conference at Melwood on Monday afternoon, Klopp revealed positive injury news on the trio ahead of Tuesday’s cup clash in east London.
Klopp said: “We haven’t decided about the starting line-up. We now have a very important session.
“[Sturridge] was fit enough to be on the bench. He was impressive in the last session on Friday night, so we thought ‘come on, if there’s a chance for 10 or 15 minutes, we should try it’.
“We spoke to him and he said he would like to. But then the game had a different story and there was no possibility with the two early changes.
“Divock and Phil will be in training today too and are in the squad, hopefully, for tomorrow.
“It’s a little bit complicated because extra-time is possible. We have to look at who will start – they can’t all start together, that’s not possible because we know we would have to change three times because the whole game would be too much in this moment.
“So we have to figure out how we do it best but we will find a solution, for sure.”
Klopp was back facing the media after undergoing surgery to have his appendix removed on Saturday and missing the game against Sunderland.
Liverpool are now 12 points adrift of the top four heading into the final 13 games of the season.
