Liverpool manager Klopp is prepared to give up his pursuit of Southampton and Netherlands defender Virgil van Dijk, 26, and put his trust in his current centre-backs.
"Look out there and tell me five that would make us stronger. Five. Then you win a prize. It's difficult how it is," said Klopp, following Liverpool's 3-1 win over Athletic Bilbao last weekend. "We have four. I don't think we need more. We cannot force the things and we would never get a centre back just because (of the sake of it).
"I'm happy. You can imagine we are still working on different things and we will see if it works. I am already here to work with this squad and not just always thinking 'but if we don't get this or this'."
