The Netherlands winger won the decisive penalty in the last 16 clash.
Bayern Munich winger Arjen Robben has admitted that he dived in the Netherlands' 2-1 win over Mexico, but not to win the last-gasp penalty.
Robben went to ground in the penalty area twice against Mexico. A penalty kick was not awarded on the first occasion, but with the score tied at 1-1 in the dying minutes he was again brought down by Rafael Marquez and Pedro Proença pointed to the spot.
Mexico manager Miguel Herrera claimed that Robben dived on three occasions, but the Dutchman said although he dived earlier in the game his tumble for the penalty was legitimate.
"Yesterday I had an interview after the game, I was very honest," Robben said. "Sometimes you are punished for honesty but I always prefer to be honest."
"There was one foul in the first half when I went to the ground because I thought he would tackle me, but in the last moment I think he took his leg away and I went to the ground without any touch.
"So that was a stupid action from me but it had no influence on the game and it had nothing to do with the penalty kick," he added.
"I apologised, it was just one stupid action but it had no influence on the game. We had two penalty situations, two clear penalties, one was given and that's it."
Robben has had an excellent tournament so far. His driving runs have epitomised the Netherlands' direct, attacking style of play, and he was in great form again in the last 16 clash.
Perhaps what is most frustrating for those who claim he goes to ground too easily is that his immense talent means there is no need for him to simulate or exaggerate contact.
The Netherlands will now face World Cup surprise package Costa Rica in the quarter-finals, after they knocked out Greece on penalties. Robben will be as important a player as ever for the Dutch as they look to advance, and the winger is not underestimating the Central Americans.
"Costa Rica has a very good team, I think they were in a very good group. They are a very strong team and it's going to be another very difficult game for us where we have to give everything to go through to the semi-finals."
