The Swans travel to Anfield to tackle the Reds on Saturday and former AZ Alkmaar man Agustien knows just what the attacking duo are capable of.
“I know Dirk Kuyt and Luis Suarez from my time back home," Agustien told his club's official website.
"Kuyt doesn't play as a striker for Liverpool, but he always scores goals. He can play everywhere and always does well.
"He works so hard for the team - he plays like he has five engines.
"Suarez is another very dangerous player, he is so tricky. He is another guy who gives everything to the team - he has the capacity of six lungs with the amount of work he does.
"He looks to have settled into the Premier League with no problems, and he has really impressed me."
