When Alisson is fit, Kelleher is very much on the bench at the Anfield club, with the Reds linked to James Trafford, of Burnley, as a replacement.
Outgoing Liverpool goalkeeper coach John Achterberg stated: It's difficult if you play a League Cup game and then don't play for two or three weeks, as you can't get into a rhythm.
"The reality is you need two good goalies to have a chance to win something and I believe we have the best goalkeeper line-up in the history of Liverpool right now.
I was speaking to Caoimh three or four years ago and told him that he was already better than David de Gea.
The only difference was De Gea was playing every week and he was getting a chance to show it.
I think Caoimh was laughing about it when I made that comment, but I always believed in him and it was just a case of him showing it day in, day out.
For a long time now, I would say he is as good as anyone in the game, but the problem here is he had one of, or maybe the best, goalie in the world ahead of him."
