It’s a debate that splits football fans like few others – who is your club’s best ever player?

Can Cristiano Ronaldo compete with Duncan Edwards? Thierry Henry with Cliff Bastin? John Charles with Ronnie Radford?

In that vein, to mark it's 100th anniversary, the Professional Footballers’ Association has published a list detailing every single league club’s best player ever - as voted for by supporters.

A quick straw poll of the office saw barely a handful agree with the result of the list – and that’s the beauty of it right? With so many to choose from, how do we fans narrow our club’s best players down to just one?

Each club’s best player according to the PFA’s poll is listed below – interestingly with the likes of Alan Shearer and Stan Bowles appearing for more than one club.

But who would you rate as your club’s best player?

And it’s not just at club level the debate rages of course – the argument over who is the best player ever to grace the international stage is as, if not even more, hotly contested.

A book published by ‘headline’ entitled “Greatest Ever Footballers” takes a statistical approach – with interesting results.

The results are based, firstly, on ‘A’ international appearances - and each appearance is awarded points that are weighted by the following criteria:
* Team played for – For example, appearances for more successful countries (Brazil and Argentina for example) count for more than less successful countries. Being in winning teams and progressing further in international competition also weighs heavier.
* More points from competitive matches over friendlies.
* Captaining your country earns more points.
* Appearances as substitute do not count as much as starts.
* Players who score goals, or keepers and defenders that keep clean sheets are awarded extra points.

Secondly, players pick up points when their team – at domestic or international level – achieves honours.

Thirdly, individual honours – such as FIFA World Player of the Year and English Football Writers’ Association Player of the Year – are also counted.

All in all, it produced a list headed by Pele – but in which George Best does not make the top 100, Romario and Luis Figo are ranked above the likes of Diego Maradona, Franz Beckenbauer and Alredo di Stefano, and Iranian frontman Ali Daei is ranked as the 26th best player of all time.

Bobby Charlton is the greatest ever English player, Pat Jennings Northern Ireland’s, Kenny Dalglish Scotland’s and Ryan Giggs is Wales’.

There are far too many issues, players and teams to pick out of the entire book to list here, but why not let us know your thoughts on the world’s best ever player? Or your country’s best ever player? Why not split them up into position? Or into decade?

If you ask me how a certain player is ranked by this book and I can answer, I will try, otherwise – get involved!
