Former Saint van Dijk has looked magnificent at the back for his new club, but appeared to injure himself late on against Tottenham in Liverpool’s 2-1 Premier League win.
Van Dijk moved to Liverpool from Southampton last year for a club-record fee rumoured to be around £75 million.
Klopp appears to think he is worth every penny, while also saying he has improved as a player since moving to Merseyside.
”He has improved us and I think he has improved since he has been here. He is a different player from his time at Southampton. He was good there but with all the different games he has played now in the Champions League, that all helps you as a player.
”That’s what you expect when a player comes in, that he makes the whole team better. He is obviously a very good player and he makes players better around him.
”He is so important to us, not only as a player but as a person as well. I couldn’t say a bad word about him even if I wanted.
”For a centre-half, he is still young so hopefully there is more to come and he can stay healthy and everything will be fine.”
