Daniel Agger has revealed how striker Luis Suarez gives the Liverpool defenders a workout in training.
The Uruguayan international has been a revelation in the Barclays Premier League after moving to Anfield in January, and has particularly impressed this term with seven goals in all competitions.
The 24-year-old's all-action style has made him an instant hit with the club's loyal fans, and Danish international defender Agger isn't surprised by the forward's performances given his efforts between matches.
"I think his performances speak for themselves. 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," he told the LFC magazine.
"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."
The 26-year-old centre back admits he doesn't envy other defenders who have to come up against the former Ajax hitman in competitive situations, with Suarez's tenacity one of his most endearing features to Reds followers on Merseyside.
It's also something which the players love to see, with Agger admitting that it provides the whole team with a boost during matches.
"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," he continued.
"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."
