After the global break, Liverpool kicked things off by losing 5-0 at Manchester City. The striker has a groin problem following Saturday's 1-1 draw at Huddersfield while Matty James (Achilles), Robert Huth (ankle) and Christian Fuchs (eye) are out.
Liverpool can now turn the mood around with the same fixture coming up twice in just a few days.
The Carabao Cup is anything but a priority for Klopp, especially given the demands of the Champions League, but it still felt alarming to see Liverpool, for whom Alex Oxlade-Chamberlain made his first start since joining from Arsenal, inexplicably lose their way in the second half.
It would be a huge surprise were Liverpool not to heavily rotate for the Carabao Cup fixture tomorrow night.
Leishman eyes wire to wire BMW Victory
He showed up at Conway Farms at No. 28 in the FedEx Cup with no guarantee of even reaching the Tour Championship. He has put himself in contention and is looking for a victory that would make this year look quite different.
It was Robertson's cross that Oxlade-Chamberlain would have converted in the sixth minute but for Ben Chilwell's timely intervention and that early attack set the tone for what followed as Liverpool laid siege to the Leicester goal.
"You are in a situation with your old club - and I don't say this about Alex specifically - and you accept it and it is hard to make the next step". I'm sure they didn't always play with three at the back and with wing backs and so Alex played in different positions when he was there. "For instance Marko Grujic made a big step in his development but no-one can see it yet, so it's really good to give him the opportunity".
Klopp announced: "I'm not sure the world is ready for such a insane decision, a third goalkeeper in one season!"
Third-choice keeper Danny Ward was forced into action when he raced out of his box to halt Slimani's run on his goal, but that apart it was the visitors asking all the questions.
Crystal Palace have broken an embarrassing record following today's defeat to Southampton
On his super Mario he said: "Mario is the style of player we didn't have before and he can help make us stronger". Hodgson's last game, that wretched defeat by Iceland at Euro 2016, was the nadir for England.
"It is a fantastic opportunity for Alex because since he has been (here) it has been hard to train on different things because of game after game after game", Klopp said at his pre-match press conference on Monday.
Liverpool duo Adam Lallana and Nathaniel Clyne are continuing to make positive steps in their ongoing recoveries from long-term injuries according to Jürgen Klopp. He had an impact when he came on.
Klopp also revealed that Joe Gomez will start at centre back if Dejan Lovren is unavailable.
Another peripheral first-team player in contention to feature for Liverpool is Jon Flanagan.
