CRISTIANO RONALDO was caught bizarrely putting his hand down his shorts and pulling something out to CHEW ON.

The Portugal captain could be seen rummaging around his shorts for a few seconds before appearing to pull something out to put in his mouth.

It left fans with one question on their mind: what was Ronaldo chewing on?

One said: "WTF you are doing Ronaldo."

Another said: "Cristiano Ronaldo making Joachim Low ver proud."

One added: "What's Ronaldo eating."

Ronaldo was caught red handed in the act, striking a resemblance to ex-Germany manager Joachim Low, who was prone to a public nose pick.

The World Cup-winning manager was also famous for scratching his crotch and sniffing fingers as well as giving Ronaldo a snotty handshake.

The legendary forward hit the headlines after his explosive interview with The Sun's Piers Morgan saw him LEAVE Manchester United.

Just two days later, the unemployed superstar opened the lead against Ghana from the penalty spot.

It kicked off a five-goal thriller which Portugal were lucky to escape 3-2 winners in.

Ronaldo made history by becoming the first player to score in FIVE World Cups - helping overshadow his bitter United exit.

He said: "It was a week that finishes the chapter, it's closed. We won and I could help the team - the rest does not matter.

"This was a beautiful moment, my fifth World Cup, We won, we started on our good foot and it is a very important win.

"The first match is crucial in these tournaments. The first player to score goals at five World Cups, this makes me very proud."
