The Three Lions defeated Qatar in their opening game of the competition and now face the Selecao, who have won both of their matches so far in Group B.
Ward-Prowse told reporters: "When we train at our clubs and when we come away with England, we are always in a competitive environment and we always want to do better. There is no point coming here if you don't want to win.
"We are here to win the tournament and it doesn't matter who the opposition is. They are all quality players, everyone looks up to them as a great footballing nation. We have seen clips of them and we will give them respect, but we want to win."
