Liverpool midfielder Gini Wijnaldum believes Holland teammate Virgil van Dijk has helped transform the Reds.

Wijnaldum has hailed Van Dijk for marshalling the defensive unit, which has kept seven clean sheets this season.

"I think Virgil has made a difference in the last line because he is a good defender, a big defender. He is an extra man who can defend set-pieces as well," he said.

"He is a leader in the last line who not only helps himself with his quality but also the players next to him and so he really helps the team."
