However, assistant manager Pepijn Lijnders has revealed that the young Irishman will continue in goal in this competition.
“As I said before the MK Dons game, with youth development, with these moments when they are in between the U23s and the first team, consistency is very important.
“He had a good game and he is preparing for another one. It will be special for him playing at Anfield.”
Jurgen Klopp has often been effusive of his praise for Kelleher and this is another statement of intent to back the youngster from the boss.
Lijnders expanded in his press conference, saying: “[Kelleher] started this competition and he’s the one who will start tomorrow.
“He’s a goalkeeper who on the line is excellent, but his calmness to play out and find a free player… for his age as a goalkeeper is very stable.
“That’s what we like about him, we see a good future for him and we want to give him this opportunity. You need these to grow and that’s why we want to give him that.”
Kelleher is a regular for Ireland under-21s at international level.
Klopp is expected to make 11 changes for the tie against Arsenal, although his options in defence are slim.
Joel Matip and Xherdan Shaqiri will miss the game due to injury, while Virgil van Dijk, Andy Robertson, Trent Alexander-Arnold, Fabinho, Jordan Henderson, Mohamed Salah, Sadio Mane and Roberto Firmino will all be rested.
