When Cristiano Ronaldo scores a free-kick, you know about it.

The 33-year-old has made his 'knuckle-ball' technique famous, scoring a number of spectacular set pieces during his time with Manchester United, Real Madrid and Portugal.

Although it isn't necessarily as accurate as the traditional curling effort, the ball movement is causes can be a nightmare for goalkeepers and results in some truly remarkable goals.

The most famous example remains his effort against Portsmouth in 2008 but he also showed his prowess from a dead-ball by scoring two in one game against Zurich and Stoke City respectively.

However, the Portuguese hasn't been so successful in recent years and his goal against Spain - albeit iconic - was the only free-kick he scored throughout 2018.

Juventus' free-kick takers

For somebody who assumes free-kick responsibilities at whichever club he moves to, that doesn't bode well and his new side Juventus have been feeling the consequences.

In Paulo Dybala and Miralem Pjanic, the Old Lady have two players with some of the best conversion rates in Europe but the amount of times they take over has dramatically declined.

Despite suggestions that Dybala and Pjanic would take efforts closer to the penalty area, Ronaldo has been assuming control for the vast majority of opportunities. 

Ronaldo's free-kick record

Considering videos would be all over the internet if one found the net, it won't come as a surprise to find out that Ronaldo hasn't scored a free-kick in Italy.

That's not necessarily a disaster but the latest set of statistics show that his conversion rate could actually be worse than first thought.

Fox Sport Asia have run the numbers and officially declared Ronaldo 'the worst free-kick taker' in Serie A having scored zero times from no less than 13 opportunities.

Ronaldo's conversation rate at Real Madrid was just over 6% but in Italy; that has declined all the way to nil. Check out the data down below: 

Oh dear, Cristiano.

It wouldn't be such a big deal if Ronaldo didn't dominate the free-kick taking, go through his usual routine and fail to produce the consistency he used to offer.

Juventus fans are also becoming increasingly frustrated when you consider Dybala and Pjanic are having to pass up plenty of these opportunities.

It must be wondered whether a crucial moment will present itself in the Champions League and Ronaldo - as opposed to a more efficient taker - misses his cue. 

The situation is definitely disappointing because, at the end of the day, Ronaldo has the ability to score free-kicks can nobody else can produce.

There's piles and piles of evidence to show that Ronaldo can score free-kicks when required yet it's been unlucky 13 for him at Juventus so far.
