For me, it goes like this (and I will give the arguments)
1 - Ronaldo fenomeno and Maradona are the best ever. If Ronaldo didnt have 2 major surgeries that robbed him of 3 years (when he was at his peak),he wouldve been considered the best ever. Guys, just check youtube and you will find that players like Zidane,Zlatan,Eto,Drogba etc...say that fenomeno was out of this world. Even coaches like mourinho and bobby robson.
Like Lenka65 said: Maradona and also fenomeno take charge of the match . Check fenomeno: even 2 defenders are not enough to stop him. The only one that humiliated goalkeepers by dribbling them and walking to the net to score.
Messi and Pele are overestimated in my opinion: Messi because ha has a huge supporting cast in the Barca, defenders has to worry about Suarez, Griezmann,neymar (before),great midfielders Inesta and Xavi,so Messi job is made easier by far .
And Pele was playing all his career Brazilian league,which cannot ranked in the top 20 in the world. So sure Pele gonna score 1000 goals. He was gifted ,had talent but no way close to those 2.
Maradona and fenomeno played in the thoughest league in the world (italy).
I wont put Messi in the top 5 ever . What skills does he have beside running with ball?
I am sure a lot guys will disagree with me
