Football fans spot Cristiano Ronaldo eat something from his shorts during World Cup match

Cristiano Ronaldo set yet another record in Portugal's match against Ghana, becoming the first man to score in five World Cups - oh, and he also scranned something he'd stashed in his shorts.

The tie was packed with dramatic moments, with Portugal edging out their opponents 3-2, after keeper Diogo Costa almost gifted Ghana an equaliser in the dying moments when he dropped the ball in the area, not spotting Inaki Williams lurking behind him.

In and amongst all the goalmouth action, there was also a low-key, odd moment that didn't go unnoticed.

Portugal captain Ronaldo could be seen rummaging around in the front of his shorts, before removing a snack and having a little munch.

I guess that's why they call it a lunchbox, eh?

It's not clear what exactly he was chewing on, but knowing the 37-year-old, it was probably some kind of energy supplement or something, rather than a Jaffa Cake or a block of camembert.

Whatever it was, you can't question the diet of a man who has remarkably managed to score at five World Cups.

Ronaldo - who is now a free agent following his acrimonious departure from Manchester United - put his nation ahead after winning his side a penalty, which he despatched in the 65th minute.

Despite things getting a little hairy towards the end, Portugal held out for a crucial three points in their opening Group H match.

Speaking after the match, Ronaldo said: "This was a beautiful moment in my fifth World Cup.

"We started with our good foot. It is very important to win. We know that in these competitions our first match is crucial.

"But also, on the record of being the only first player in five World Cups to score, that is something which makes me very proud.

"I am very happy that the team got a good result, it was a tough game but a good result."

Ronaldo - who was named the official player of the match - took just one question from reporters, only touching briefly on his fall-out with United.

"It was an important step and we won," he said. "It was a week that finished this chapter, it is closed.

"We wanted to start off with the good foot. We won, I could help my team – and all the rest does not matter."

Portugal coach Fernando Santos praised the influence of Ronaldo.

"He is one of the best players in the world, one of the finest goalscorers of all time," Santos told a press conference. "His achievements, one of the best players of the world, one of the best players ever.

"Cristiano is a phenomenal legend, like many others have come and gone. In 50 years' time we will continue to talk about him.

"We talk about Pele and Maradona who played 50 years ago and so I think we will continue to speak about Ronaldo like the other players I speak about."
