Unfortunatelly we didnt comeback since the 7x1, we had the chance this world cup, but as seen we weren't in that level. Hopefully we will be for the next world cup.
By the way, the example I exposed about football was from ronaldo's injuries and harsh loss against France at the final, the amazing run to become the best player and world champion. I think you can say the same for Pele, he didn't had a injury, but what motivated him to be a pro player was the Brazillian loss against Uruguay in 1950 final, and as we know he is 3 times world champion.
1994 its the only year that we were champions and there was no comeback, maybe just Romario proving himself as one of best players in the world.
