Liverpool have signed Klavan from Augsburg for £5 million.
The 30-year-old played 140 times for the Bundesliga club and scored 4 goals.
Ragnar Klavan announced in his first interview that he's very happy:
"I'm really honoured to be part of this amazing club and amazing team. It's hard to put it into words because it's been a dream of mine for 22 years to come to the Premier League and be part of this amazing club, Liverpool.
"What excites me is the history, how many trophies they have won and then the kind of names that have been here in Melwood and at Anfield. That I can be part of this - I can't describe it - it's something special and I'm privileged to be here.
"Mart Poom was the first Estonian to play in the Premier League and he was a big idol for me when I was growing up. I followed him wherever he went so that's one of the reasons, but the Premier League is the most attractive league in the world and there are always amazing players here. It is the home of football.
"In the beginning, you are more focused on the atmosphere and what's going on because it is a really good stadium and the fans are amazing," the defender said.
"At that time, we also had a lot of fans from Augsburg and this combined to make a really good atmosphere.
"I think it's more the feeling you get when you walk on the pitch. It's a compact stadium, but there is so much history in there and this is what excites me more.
"Nowadays, teams are in really new stadiums that looks good and everything is clean, but with Anfield, there is a lot of history in there. It's not the newest but it is the place to be.
"For me, the most important thing is the team effort and whatever needs to be done for the team," he added. "I've always been a team player and it will be the same until I retire.
"We will see but of course, if you come to this big, amazing club like Liverpool then there's a lot of players who are really good players".
