Netherlands goalkeeper Tim Krul insists he did nothing wrong in confronting Costa Rica's penalty takers during a World Cup quarterfinal shootout.

Krul's crucial two saves on Sunday night followed his novel tactics that tested FIFA's guidelines on fair play. The substitute goalie faced up to opponents at the penalty spot and repeatedly told them he knew where they'd place their shots.

Krul says: "I don't think I have done anything wrong. I haven't shouted at (them) in an aggressive manner."

He says: "I am trying obviously to get into their heads and it worked."

The Dutch team's 4-3 shootout win after a 0-0 draw set up a semifinal against Argentina.

Krul says he would do the same again in Wednesday's match.
