While Real Madrid sit sixth in La Liga, their all-time top scorer Cristiano Ronaldo has been firing Juventus to an eight-point lead at the summit of Serie A.

CR7 took a bit of time to settle in at his new club but he's now registered ten goals, five assists and, most impressively, ten Man of the Match awards, in 16 matches.

From Leonardo Bonucci and Miralem Pjanic to Paulo Dybala and Mario Mandzkuic, Ronaldo has formed understandings all over the pitch with his talented new teammates.

The 33-year-old opened the scoring against SPAL on Saturday to become the fastest player in Juventus history to score ten goals in their debut season at the club.

The forward produced the famous shout of "Siu" when celebrating his goal, but he then whipped out a pretty bizarre second celebration which only fan footage seems to have captured.

Cristiano's 'second celebration' against SPAL

For several years now, we've all become familiar with Cristiano's celebration: he jumps up, spins in mid-air and shouts "Siu" as he lands, with his arms outstretched.

In fact, viewers of Juventus 2-0 SPAL noticed that the home supporters joined in with Ronaldo's chant after his clinical 28th-minute strike at the Allianz Stadium.

That said, when most TV broadcasters were probably showing replays of his goal, the £99.2 million summer signing unveiled a second celebratory gesture.

As you can see in the video below, the Portugal captain raced away to enjoy his fine left-footed effort in the usual fashion and receive embraces from his teammates.

Then, after a quick hug with Douglas Costa, Cristiano bent his knees and went up and down twice in some sort of squatting motion.

What was that celebration all about?

Seeing as he pointed up to the stands shortly after the pose, Ronaldo's "second celebration" against SPAL could've been for someone in his family.

It could be a signal to his work in the gym, some form of training or warm-up stance, or simply a bit of fun for Juve's fans to enjoy - time will tell if he decides to do it again in the future.

One thing that is definite is that the five-time Ballon d'Or winner seems to be loving life in Turin and his attention now turns to Champions League action.

Juventus lost 2-1 at home to Manchester United in their last outing but they can guarantee qualification to the knockout stage by beating Valencia on Tuesday.
