Neymar last week wrote off the Three Lions' World Cup hopes.
But Rooney's goal in Sunday's 2-2 draw in Rio forced the Brazil star to rethink.
Neymar, 21, said: "I will change what I said. England do have a chance at the World Cup but only if they can find 10 more Rooneys before then.
"He is one of the best. His technique, his strength, his ability to score many goals - he could be Brazilian.
"He is one of the best players in the world but no player can win a World Cup on his own."
