Liverpool boss Jurgen Klopp is seeking top drawer quality in the summer market.

But Klopp has warned it will be difficult to find players who can improve his side.

Southampton centre-back Virgil van Dijk and Naby Keita, RB Leipzig's all-action midfielder, are amongst those at the top of the German's list.

“We have to be better next year and we will be," he told The Times. “For this we need to bring in quality players. Believe me, it is not easy to find players who make us better. We are already good.

“We will find them because I love the combination of Liverpool: the name, the size of the club, the support, the power, the money we can pay, stadium we have, the atmosphere we can create, I love it. It's the biggest ever."
