But after fans criticised Neymar, 26, for going down too theatrically, the World Cup-winner had some words of advice.

Maradona, 57, told Marca: "Neymar is a star player too. He is still lacking something but he is a star.

"He has to know that today diving is a yellow card and VAR exists.

"He already had one taken away against Costa Rica. Neymar has to change the 'chip' in his head a little bit."

Maradona was asked if he still believes Cristiano Ronaldo is a star player after Portugal were knocked out by Uruguay.

And he threw his support behind the five-time Ballon d'Or winner, who has been linked with a Real Madrid exit.

The Argie icon added: "Well, that is a silly questions because he is clearly a star player. He truly is, there is no doubt.

"If Cristiano has to stay at Real Madrid or not he has to decide, I am not getting involved in that.

"Ronaldo has people by his side who know how to advise him and they will give him the best advice possible."
