The former Augsburg defender joined the Reds last week.
“I've heard that people have been talking about (Ragnar) Klavan as our fourth option (at centre-back). Wait and see him play and then tell me again that he should wait until all the others are injured or something," said Klopp to the Liverpool Echo.
“Ok, it's a little bit different with Alex (Manninger). He knows his role as something of an educator for the boys.
“But he gives us opportunities to feel secure with a No 3 keeper to help John (Achterberg) with all the goalkeepers around and to allow us to send Adam Bogdan, Ryan Fulton and Danny Ward on loan, and keep Shamal (George) here to play for the under-21s. That's quite cool."
