Liverpool defender Virgil van Dijk has been warned by Netherlands boss Ronald Koeman about his future.

The centre-back is not enjoying the best of seasons for his club, while he was below par at the World Cup as well.

Koeman, who took over from Louis van Gaal after the winter tournament as the Dutch coach, has warned Van Dijk he must find his top level soon.

Koeman told Studio Voetbal: "Still, but it [Van Dijk] will have to be better. We are well endowed with central defenders."

He added: "Of course he got injured. A knee injury, a muscle injury and then a World Cup played in November, but I think his lesser form also has to do with the team he plays in.

“Liverpool was known for putting pressure and winning balls in midfield, so Virgil also got into less trouble. The chance of mistakes has now become many times greater.

"Of course he [Van Basten] is allowed to criticise. I also have that on Virgil. I have always said to Virgil: 'You should always assume that the player next to you makes a mistake'. Then you have to look: am I good? Good at the situation? Sometimes he just has to enter the game much harder and shorter, but then he keeps his position too much. I also discuss that with Virgil."
