Liverpool goalkeeper coach John Achterberg says Caoimhin Kelleher can "be anything".
The 20-year-old was impressive on debut in the win MK Dons a fortnight ago.
And Achterberg sees huge potential in the Republic of Ireland U21 international.
"I was proud and happy for him because he shows every day in training his speed and reactions," Actherberg told the Liverpool Echo.
"That is why he is in the Irish squad and they thought that he can give the No.1 in Ireland big competition but he needs to play games to show.
"By making this appearance [against MK Dons] he can make big strides and steps. He reads the game and plays well with his feet for Liverpool. But he shot-stopping and his reactions is massive for any club, I would say. This is where he is good and it is what he showed against MK Dons.
"He can keep making the next steps and how far he goes is how he can producing these displays on the field because that is where you are going to be assessed. In my opinion, he can be anything. It depends how he develops.
"In an ideal world you have three top goalkeepers but maybe at third choice you have an experienced keeper or a young talented boy who can step up.
"There are two talented boys at the academy but they are still some way off. Vitezslav Jaros and Jakub Ojrzynski, they still have to improve to get to the level of first team."
