He is regarded by many as the best footballer on the planet, and now Cristiano Ronaldo is doing the business off the field as well.

The 33-year-old Portuguese superstar took to Twitter on Thursday for his latest #CR7Underwear range – FW18, and showed off his six-pack in all its glory.

“Always on the ball,” Ronaldo tweeted above a photo of him lying among plastic balls.

The Sun quoted Ronaldo as saying: “This was one of the most fun shoots ever. I’m a big kid at heart and it’s not every day you get to jump into a giant ball pit.

“CR7 Underwear makes you both look and feel good, so I wanted the new campaign to capture that and have a fun and light-hearted feel.

“Underwear is the foundation to any outfit so perfectly cut, premium quality styles are essential to helping you stay on top of your game.

“My new Fall/Winter range combines optimum fit with cool, edgy design in some of my favourite colours.”

Ronaldo was given a break from international duty for Portugal in the UEFA Nations League over the last week, but should be back on the field for Juventus against Sassuolo in the Serie A on Sunday (3pm SA time).
