Cristiano Ronaldo was back on the scoresheet after drawing a blank in Juventus' 2-1 defeat to Young Boys.The Portuguese superstar grabbed the crucial opening goal in the Turin derby against Torino after a frustrating evening for Juventus.Ronaldo had previously shanked a free-kick out for a throw-in during the first-half, with the likes of Emre Can and Miralem Pjanic struggling to set the tone in midfield.However, the Bianconeri made the breakthrough on 70 minutes, with Ronaldo converting from the penalty spot after a foul on Mario Mandzukic.Few players in the history of the game have been as prolific as the 33-year-old from the spot and he made no mistake this time.However, his celebration after the spot-kick will certainly raise a few eyebrows.Straight after he had lashed the ball past Salvador Ichazo - who had replaced the injured Salvatore Sirigu - Ronaldo appeared to chest bump the Torino goalkeeper.You can watch the footage below.

Not a very professional attitude from the Portuguese.

While it certainly wasn't a violent push, it was rather unnecessary from Ronaldo and he was duly booked by the referee for his actions.

Whether Ichazo had said something during the game or just before Ronaldo took the spot-kick is unknown.

Juventus are now eight points clear of second-place Napoli in the Serie A table and look set to scoop yet another Scudetto.

The main goal for the Bianconeri will be to add the Champions League trophy to their domestic accolades come the end of the season.

Juve lost in both the 2015 and 2017 finals, but the signing of Ronaldo has led many people to label the Italian side as the favourites for the competition this time around.

You wouldn't put it past them, but Manchester City, Liverpool and Barcelona may have something to say about that come the end of 2018/19.
