There are very few footballers - past and present - who can lay claim to being an all-time great.
Where the past is concerned, the likes of Zinedine Zidane, Raul, Ronaldinho, Brazilian Ronaldo and Sir Bobby Charlton can all stake a place in that category.
As for the present, Lionel Messi, Cristiano Ronaldo, Andres Iniesta and Zlatan Ibrahimovic are all considered as legends of the game.

However, in the aforementioned Ronaldinho's eyes, there are only two individuals that genuinely constitute as all-time great footballers.
Interestingly, neither Messi or Ronaldo feature in the former Barcelona forward's two-man list.
He told AS: "In the history of football, I only look at [Diego] Maradona and Pele. Both are world football greats."
Maradona and Pele are both sure-fire legends of football having won four World Cups between them during their respective careers.
And perhaps that's the difference between them and Messi and Ronaldo, with neither of the two having won football's biggest tournament.
Messi came agonisingly close to lifting the FIFA World Cup Trophy with Argentina in 2014 but fell second best to Germany in the final, courtesy of Mario Gotze's extra-time strike.
What's certain is the Barcelona striker and Ronaldo are all-time greats from this era, with the pair about to go head-to-head once again for the Ballon d'Or.
Real Madrid's superstar is favourite to be named the world's best player for a fourth time but for Ronaldinho, it should be Messi who wins the coveted prize.
"All the players have done a brilliant job, it is tough to choose," the Brazilian added. "Ok, I will be honest with you, I am backing Messi!
"I am delighted to see him happy, if he made the decision to come back to Argentina and he is happy so am I, because I am his friend."
Let's face it, Ronaldinho was never going to choose Ronaldo over his former teammate.
