Sporting debates don't come much bigger than Cristiano Ronaldo vs Lionel Messi.
While past eras in football have largely been defined by a stand-out player such as Pele or Diego Maradona, the last decade has seen world football's number one switch every other year.
It's such a strange situation that, for many, deciding the best player in the world right now has become the very same debate as naming the greatest in history.
Simply put, both Ronaldo and Messi have been eclipsing every record under the sun in recent years and they're almost inseparable down to the number of Ballon d'Or wins.
Some fans will argue that Messi is the GOAT (greatest of all-time) by citing his incredible dribbling, humility and the sheer beauty of his style of football.
Messi vs Ronaldo
Meanwhile, those in the Ronaldo corner will refer to his almost incomparable goalscoring exploits, work ethic and a physicality that surely makes him the sports most 'complete' player.
For the time being, football fans can focus on this season and a campaign approaching a Ballon d'Or ceremony that could end the Ronaldo-Messi duopoly.
But who's been on top when you remove the likes of Luka Modric and Kylian Mbappe from the argument?
Individual performances compared
Well, one particular journalist has taken that question very seriously and has directly compared the individual performances of Messi and Ronaldo against each other in the league.
John Molinaro has been keeping readers of Canada's SportsNet updated with the pair's displays, coming to an eventual conclusion and maintaining a running tally.
And with the 2018-19 season now well underway, the results look very interesting indeed. Check out a comprehensive breakdown below:
Matchday one: Lionel Messi
Matchday two: Cristiano Ronaldo
Matchday three: Lionel Messi
Matchday four: Cristiano Ronaldo
Matchday five: Cristiano Ronaldo
Matchday six: Lionel Messi
Matchday seven: Cristiano Ronaldo
Matchday eight: Cristiano Ronaldo
Matchday nine: Lionel Messi
Matchday ten: Cristiano Ronaldo
Current result: Cristiano Ronaldo 6-4 Lionel Messi
Despite many perceiving Ronaldo to have made a slow start at Juventus, he kept close to Messi and has started to pull away with his brilliant recent form.
It's very interesting to see the pair's individual performances directly assessed and each article goes into an impressive amount of detail that would be too much to go into here.
Nevertheless, it goes to show that Ronaldo has made the finer start to the season and would be the leading candidate of the two to lift the Ballon d'Or.
And after winning the Champions League with Real Madrid earlier in the year, he certainly has a decent argument going forward.
That being said, the bookmakers believe it will be Luka Modric adding the Ballon d'Or to his growing trophy collection, despite a tough start to the season.
Even if the Croatian takes the glory, though, it won't shift the attention from a debate that continues to shift with every single performance.
