Neymar has already scored three goals during the eight-team tournament, and he has revealed that he would like to add to his tally against one of the "greatest" goalkeepers in the world.
The 21-year-old told AS: "I have always had great admiration for many players. Casillas is one of the greatest keepers in the world – now and always.
"I have huge respect and admiration for him. Everyone would love to have him in their side, but on Sunday, I hope to have the honour of scoring against him."
