Mohamed Salah and Cristiano Ronaldo are icons in the world of football.
The pair are recognised across the globe for their sporting achievements and contributions on the field, having performed at the highest level for most of their careers.
The former has 148 league goals to his name at the age of 29, while the latter - who is aged 36 - has an impressive total of 428 league goals already in the bag.
Their offensive impacts are largely unrivalled and they will clash at Old Trafford on Sunday afternoon as Liverpool meet Manchester United in a high-profile Premier League bout.

Salah and Ronaldo each have the quality to decide the contest with a moment of individual brilliance, but a specific element places the two players at opposite ends of the scale.
Under Jurgen Klopp, Salah has evolved to become the ultimate wide forward. He ticks pretty much every box, even when it comes to his defensive work.
So far this season, only Brighton's Neal Maupay has showcased more pressures in the final third than Salah's total of 68, and the story was similar last year.
During the 2020/21 campaign, Salah placed second once again in England's top-flight, with his total of 343 pressures ranking him behind only Ollie Watkins of Aston Villa.
On a per-90 basis, Salah averaged 10 pressures in the Premier League last season and this time around, he's posting 8.5 per 90.
Ronaldo, on the other hand, operates differently when he's without the ball.
The Portuguese forward has amassed a total of just six final third pressures during his time on the field so far this season, averaging 1.4 per 90.
For perspective, his 1.4 final third pressures per 90 is less than the averages posted by the likes of Ricardo Pereira, Abdoulaye Doucoure, Nelson Semedo and Pierre-Emile Hojbjerg to name but a few, even though each of those players are recognised as midfielders or defenders.
Ronaldo is renowned for delivering goals but as a result of his status in the game alongside his age and United's stylistic approach, he seems to be presented with a luxury status when his team are defending.
The Red Devils legend has to be carried by his teammates as a defensive passenger, whereas Salah is very much involved in Liverpool's pressing game despite his ability to win games almost single-handedly.
Pep Lijnders - Klopp's assistant - once said: "Avoiding goals takes 22 feet and two gloves. As a whole team, we have to defend."
That won't change this weekend but when it comes to the approach of their arch rivals, it is likely that Ole Gunnar Solskjaer will have to find a way of carrying his biggest name.
