Real Madrid star Cristiano Ronaldo has starred in a Japanese advert endorsing a workout gadget designed to work on facial muscles.

The Portugal captain has attributed his name to many products over the course of his career, including watches and underwear, but it appears that the 29-year-old has gone down a different route in Japan.

In the ad, which has been uploaded to YouTube, Ronaldo is seen showing off some fancy footwork before presenting the gadget to the camera.

While the player himself did not demonstrate the PAO gadget, Ronaldo is joined by a number of people in the ad showing how the tool works.
