The Reds on Thursday announced they had agreed a deal with Southampton for Van Dijk, who will become the world’s most expensive defender when he completes his move to Anfield on January 1.
Many have questioned the Merseysiders’ willingness to spend such an amount on the Netherlands international but Klopp is preferring to let his performances do the talking.
Klopp told Sky Sports: "Quality. That's why we got him, that's why we were interested in him. It's quite difficult at the moment because technically he's still a Southampton player.
"We don't make the prices, the market does. Liverpool supporters should forget about the price.
"We only talk about the player and what he can bring in; the quality, the mentality, the character. That is why we are really happy about it."
