"I had an amazing time at FCA but I've now been able to fulfil a childhood dream by moving to England," said the centre-back. "I would like to thank all of the management at Augsburg for allowing the transfer to go through. I got an impression of Anfield when I played there with FCA in the Europa League in February. I am looking forward to experiencing that regularly now."
Estonia captain Klavan made 125 appearances for Augsburg across four seasons, scoring four goals.
