WATCH: Cristiano Ronaldo debuts new celebration in win over Luxembourg

Cristiano Ronaldo brought out a new goal celebration after netting in Portugal's 6-0 thumping of Luxembourg on Sunday.

The veteran forward captivated the attention of the world with his viral SIUU celebration - jumping, spinning and shouting along with the crowd - during his time with Real Madrid and later brought the same move to both Juventus and Manchester United.

With United, Ronaldo unveiled a new celebration which saw him cup his hands together over his chest and tilting his head back, as if he was taking a nap.

He took both celebrations over to Saudi Arabia when he joined Al Nassr and has switched between the two, but Ronaldo took a different approach when he scored against Luxembourg for his country.

Instead of choosing between his two trademark celebrations, Ronaldo opted for both.

After tapping home from close range to open the scoring, Ronaldo charged towards the corner and pirouetted to kick off his SIUU celebration, but as the crowd began to scream along with him, the striker switched into his nap pose.

Ronaldo still decided to scream along with the crowd as he lay his hands on his chest and closed his eyes, mixing the two celebrations for the first time.

It's not the first time that Ronaldo has mashed up two celebrations, having done so on occasion during his time with Juventus.

In Turin, Ronaldo once wound up for his SIUU cheer before copying the mask gesture popularised by then-teammate Paulo Dybala.
