The Brazilian's only appearance for Liverpool arrived when he came on as an injury-time substitute during last week's win over Paris Saint-Germain, although Klopp has reiterated that the Brazilian has needed time to adjust to his tactical concepts.
Unfortunately, a reported injury to Ruben Loftus-Cheek will keep him out for Wednesday's game so Ethan Ampadu may get a chance to impress.
"So, that's the line-up and all the guys in defence, where we changed the most, really deserve to play". They are here because of what they did.
"To improve something, you need half a year to make the next step".
Klopp has made an omission about what his team will look like in an interview with Liverpool FC: "Simon (Mignolet) will start, all the rest you have to wait until tomorrow - but it will be a good team, believe me". "They were all used to other football teams".
It is not the Premier League, but who we are we want to play the games as best we can.
"He is right. We work longer together", Klopp added. Roy Hodgson's XI was full of players with little or no chance of getting into his first team - and it showed all evening.
"That's why I said it's quite impressive what he did in that short period (since taking charge at Chelsea)".
Just how serious those ambitions are will become clearer over the next two weeks as Liverpool faces Chelsea twice (Wednesday in the Carabao Cup, Saturday in the Premier League), travels to Napoli in the Champions League (Oct. 3) and then faces City itself in a return to league play (Oct. 7).
As a result, the new man in charge has been forced to make drastic tactical changes in order to match his needs, and the results have astonished Klopp. "We are trying to have him at the end of the week, but I don't know at the moment".
"If you're going to win the Premier League this year, you're going to have to finish above Liverpool".
"It is a completely different competition and a coincidence that we play them again in a few days".
"He can not be settled, but it's a good thing that Millie, Naby and Fabinho played together in this formation in pre-season".
"If I see one player tomorrow who goes into the game and I have the feeling he thinks "it's only the League Cup" then he could have a real problem".
