The Paris Saint-Germain forward has assumed a talismanic role in Qatar, with his return of six goal contributions — four goals and two assists

Brazil great Ronaldo says Lionel Messi's incredible achievements do not mean he deserves to win the World Cup, and that the Argentine captain must earn his shot at glory.

Messi provided a goal and an assist as Argentina overcame the Netherlands in the last eight, and he will hope to lead to their sixth World Cup final when they meet Croatia in Tuesday's semi-final.

Messi has both scored and assisted in two different games at this World Cup, and in three at the tournament overall. Since 1966, no player has done so on four occasions.

While praising Messi's performances, Ronaldo warned that lifting the World Cup would not come easily for the seven-time Ballon d'Or winner.

"Argentina isn't playing very well, but they play together, they're aggressive and then there's Messi, who is decisive when he's near the box. He now does less sprints than before.

While Argentina remain in contention for a third World Cup triumph, their great rivals Brazil crashed out in the quarter-finals, after losing a dramatic penalty shoot-out against Croatia.
