The Manchester City midfielder was fully aware of the impact of the Selecao's defeat, while Maicon wants his team-mates to move on as soon as possible
The South Americans were desperate to banish the memories of 1950 from their minds - when Uruguay beat them to the World Cup on Brazilian soil - only for another nightmare to ensue.
"I think we're all aware that it was an 'impossible' result. This match will be remembered forever," Fernandinho told SporTV.
"The atmosphere is not very good after a defeat like this, not good at all. Our dream has ended in a very harsh way."
Fernandinho then went on to stress that Brazil must try and move on from Tuesday's defeat and get ready for Saturday's third-place playoff in Brasilia.
"We need to have personality, raise our heads and try and live with this. I think the professionalism of each of us, our character and honor and the pleasure of doing what we like most is what is going to help us through the next three days.
"We are going to to fight for third place the best we can on Saturday."
Meanwhile, veteran defender Maicon was left speechless after Brazil's shock-defeat, but urged his team-mates to try and move on as quick as possible.
He said: "This is one of the worst days of my life, but we have to move on. It's a moment of sadness. Suffering seven goals, that's just ...
"In four years we'll have another World Cup, Saturday there's another game, we need to get over this because it will be remembered for a long time.
"Everyone's sad. Fans, players and families... But Saturday is another day and we'll have to close this the best way we can. I have no doubt that we'll be ready for Saturday."
Brazil will meet the loser of the semi-final clash between Argentina and Netherlands in Saturday's match at the Estadio Mane Garrincha.
