The Uruguayan striker's ability to take on players has caused defenders plenty of headaches in the new Barclays Premier League season - including Agger, who has to try and stop Suarez during Liverpool training sessions.
Agger has been so impressed by the ability shown by Suarez that he even has a touch of sympathy for his fellow centre-backs in the league who have been tasked to stop Liverpool's star striker.
"I think his performances speak for themselves," Agger told LFC Magazine interview this week.
"Everybody can see that he is a class player. He is so different. I cannot find any other striker that looks like him or plays like him.
"It's not because he does any fancy things or anything like that, he just gets the ball in front of goal and creates the chances for himself. Sometimes the way he gets the ball and the way he gets in on goal - you don't believe it.
"But all credit to him and if he can continue like that, he is definitely going to be one of the world's best.
"He does it every day in training, so we know how hard he is to play against. People can see every Saturday afternoon that defenders are struggling to keep him at bay.
"It gives everybody in our team a boost to know we have someone like that in attack. To achieve something, I think you need players like that in your team."
The Liverpool website notes that Suarez has created 19 chances in league competition this term as well as 43 shots.
However, Suarez has only managed four goals in the league so far despite his good form.
