The game of football has changed throughout the ages.
We've moved into a position in the 21st century where it's difficult to draw the line between winger and forward, but 50 years ago it was far more clear.
If one of your favourites isn't on here, he may well have been classed as a forward. There's no exact science to it, but I've determined it to the best of my abilities.
Some obvious absentees are Alfredo Di Stefano, Lionel Messi, Cristiano Ronaldo, Ronaldinho and Kazimierz Deyna, who fall victim to this thought process.
Franz Beckenbauer is also missing, as although he played in midfield for some of his career he is labelled primarily as a defender. The same applies to Obdulio Varela, and they both featured in my 50 Greatest Defenders in History article.
Please also be aware that this set of 50 players is not ranked. When it comes to the cream of the crop, who am I to tell you who's best? It's a very subjective topic, and everyone has their own favourites—it's what football is all about.
As such, there are no rankings, no numbers and the players are randomly placed.
