Haha no they dont do everything for him. He does more to help that team win than anyone else.
In past have heard Di Maria was their best player and reason they won, now its some other players. The constant is him and he did it at Man Utd as well.
Same as when Messi had prime Xavi/Iniesta who were better than this Real sides supporting cast bitter folk would claim Messi had it easy.
Ronaldo has produced year after year in different teams with different supporting casts as has Messi.
But Messi has been better overall.
They are different players.
Messi is one of a kind, hes not a striker, hes not a midfielder, hes not a winger. He can do it all, and thats what makes him the best imo.
What can Ronaldo do other than scoring and running fast in a straight line? not much.
Any player needs good players around him to open up space for them.
As we see now Messi is totally isolated with this team, while Ronaldo has alot of great players to support him.
Even with Xavi/Iniesta Messi is more of a creater and contribute more to the team than Ronaldo ever did other than scoring.
Ronaldo has been worse in the national team than Messi, where he doesnt get support, for example.
Ronaldo couldnt drive Real Madrid during the years they had a crappy team. The only time he won ballon during those years, were becouse of Messis injury.
So no, i wouldnt say Ronaldo has "proven" anything in alot of teams.
Still, they are far ahead of the third best player if you see over the 10 last years. And they probably wouldnt be as good if the other didnt exist.
