The Brazilian says he has been doing extra penalty practice ahead of the Champions League final against Liverpool on Wednesday.
He said: “I wanted to die because we had a 3-0 lead and had control of the game. I still cannot understand how it went away from us.
“It was one of the saddest moments of my career, but now we have the chance for revenge.
“I have faced many penalties this week, but I don’t believe it will come to that as the game will be decided a lot earlier.”
