"I couldn't care less about others," Ronaldo said in the mixed zone on Tuesday when asked about Messi's five goals in the opening two games of the World Cup …Mbappe also scored."

As much as the Portugal forward may say otherwise, seeing the biggest stars in world football come to the fore at this tournament would have been a source of motivation. Especially Messi.

"I believe both players have improved football over the years, and their rivalry is important for themselves to grow," Martinez conceded.

"He wants to be the best at what he does," Rooney said of Ronaldo's attitude towards Messi. "So, of course, when the other top forwards are scoring goals, he wants to be top of that list. His response here is exactly what you'd expect.

"He's selfish in the sense that he wants to be the best, but he's a team player also. It's incredible to watch Messi last night and Ronaldo tonight. At their age, it's incredible what they are doing."

Ronaldo and Messi have both had to adapt their games to stay at the top.

Since turning 35, Messi has found a new level on the international stage, scoring 12 goals in his last nine World Cup matches. That's two more than Ronaldo's total of 10 and would place him seventh on the all-time World Cup scoring list, level with Brazilian icon Pele.

Messi had scored just six in his first 19 games in the competition, between the ages of 18 and 34.

The turn in form has happened since leaving Barcelona. It could be argued since leaving the Catalan club, he may have prioritised playing for Argentina. Many from his country argued that he had not when competing at the top of Europe in his peak years.
