As the second round of fixtures gets underway at the World Cup it's starting to look like the tournament could end up belonging to Cristiano Ronaldo.

Four goals in two games makes the 33-year-old the top goalscorer in Russia at the moment, one ahead of Spain's Diego Costa and Russia's Denis Cheryshev.

His hat-trick in Portugal's opening game against Spain was stunning, especially the last-minute free-kick, and he was once again the hero in Wednesday's 1-0 win over Morocco.

Portugal next face Iran in five days' time - a fixture Ronaldo will be licking his lips at in his current goalscoring form.

Winning the World Cup would be a dream come true for the Real Madrid man and would all but guarantee a SIXTH Ballon d'Or at the end of the year.

And doing that, of course, would see Ronaldo go one ahead of long-term rival Lionel Messi.

Ronaldo and Messi are both in their 30s yet their rivalry is as fierce as ever and it's still debated who exactly is number one.

THE GREATEST RIVALRY

For years it was thought Messi was top dog, but it's hard to ignore what Ronaldo has achieved in recent times. He's probably more deserving of the crown on that basis.

But what does Roy Keane think? Well, speaking on ITV on Wednesday, the ex-Manchester United captain said something he never thought he would say about Ronaldo and Messi.

Keane is a huge fan of Messi but he now claims he would have Ronaldo over the Argentine because Ronaldo has "gone onto another level".

"I think there's been great debate over the last few years with him (Ronaldo) and Messi," he said on ITV. "But over the last six months I think he's gone onto another level.

"I think he's out there on his own, the way he's started the World Cup, the way he finished last season.

"How many times can we say it about him? His improvement, his attitude, and I think a lot of it is not natural ability for Cristiano Ronaldo.

"As brilliant as he is, I think it's just sheer hard work, determination, desire. Today for the goal [against Morocco], courage, he's got a lot of courage, wants to get in there, he's brave.

"I've said it before, the guy's a genius. In this form at the moment, over the last few months, the way he's started the World Cup, I'd have him ahead of Messi.

"I never thought I'd say that because I love Messi as well. It's a good debate to have, but his form at the moment, he has just taken a step ahead of everyone, including Messi."
