Actually I don't really understand why ppl compare Pele & Maradona, two careers that are 10-20 years apart?

Pele - best of his generation
Maradona - best of his generation

If memory serves me correct, came in Johan Cryuff between the two. Cryuff would be second to both Pele & Maradona at different era.

George Best could probably give Cryuff a run for his money.

Zidane - no challengers hands down during his era. You could argue the Brazilian Ronaldo or Romario

Let's not forget Roberto Baggio - a very intelligent player. He was probably Pele & Maradona in one tho less appreciated maybe because he didn't win major titles.

Now at let's come back to this era of football. Messi & C.Ronaldo both lit up the footballing stage way, way earlier than Suarez. If either one of Messi or CR had been born in different generations, they would be the best in their own right.

Suarez, great footballer, great goalscorer, but I am not yet convinced that is on par with Messi or Ronaldo.

Keep in mind that Ronaldo plays as a winger and is only an out and out striker when RM is 3 or 4-0 up, or if they are trailing. He is still considered a goalscoring winger. Suarez's bread and butter is scoring goals. So I am not going to compare their goalscoring records.

So having said that, we can't really say who is the best among those that are currently still playing. If you look at goals + titles, then definitely Messi but that is probably inaccurate measurement to use as this is all relative.
