The Greek centre-back, a cult figure amongst Liverpool fans, has been impressed with what he's seen of Kelly.
"Kelly is a very good player," said Kyrgiakos.
"He played several games last season before he got an injury but he's played more often this season and done very well.
"He knows he can improve because he is a young player but he has a good attitude, always wants to learn, and if he can stay focused then he he can be a really good player for Liverpool."
