Liverpool assistant manager Pep Lijnders has declared goalkeeper Caiomhin Kelleher as "world class".
The Irishman acts strictly as cover for Alisson Becker at Liverpool.
But Lijnders argues: "I think the best signing of the season is Caoimhin - that he stayed with us. In my eyes, he is a world-class goalkeeper and he needs games, which he will get.
"And Alisson has a huge part in how Caoimhin has developed. He deserves great, great credit for Caoimhin's development.
"Yes, we have a world-class goalkeeper who, in my eyes, can play for any Premier League team."
