The Brazilian defender says scoring the winner was one of the finest moments he has ever experienced, while Jurgen Klopp prepares his team to face Greuther Furth
In a frenzied final few minutes, the 6ft 4in defender popped up to make it 3-2 to the Germans on the night and put them through to the semi-finals where they now await Real Madrid.
BVB had to come back from behind twice after goals from Joaquin and Eliseu put los Boquerones in front. However, the German club overturned the deficit to seal the tie in an astounding injury-time climax.
"I do not know how many times I've seen the goal now - but every time i see it I am always happy as a little child," the 27-year-old told Bild.
"I have never received so many calls and text messages as after this game. This is madness. When I got off the phone with my father after the game, he cried so loud that I could not understand a word."
The Brazilian defender won the Bundesliga title in 2012, but says that goal felt just as good.
"They are two events that I will never forget," added the former Figueirense man.
Now that the destination of the Bundesliga title has been firmly wrapped up, Jurgen Klopp's men are now looking to ensure they finish the season in second place by taking maximum points from their remaning six games.
The former German champions take on Greuther Furth this weekend and Klopp says they still have to keep playing well domestically, but will leave it as late as possible before naming his starting XI.
"We still have targets in the Bundesliga," the 45-year-old told the official club website.
"Saturday sees the conclusion of a long week with three matches, but this time we don't have to play again three days later.
"We have to wait and see who´s fit and ready and then field a good side."
Furth are bottom of the German league and have almost no hope of retaining their top flight status next season, but BVB's coach says it will still be a challenging match.
Klopp added: "There has been a complete change of sentiment in Furth. They can play now without any pressure, so it's going to be a difficult and intense game."
