An excellent long pass from Wesley Sneijder sent Robben away on the right flank, where the left-footed player cut in and went past two Slovak defenders to put the Dutch ahead with a well placed shot inside the near post.
It spurred the Dutch to a 2-1 win that earned them a spot in Friday's quarter-final in Port Elizabeth, their first since 1998 when they finished fourth.
"I think I've scored a few goals like that, I'm left-footed and I play on the right side. A lot of the time I go inside and look for the shot," he told a news conference at the Moses Mabhida stadium in Durban.
'RIGHT TIME'
"I waited for the right time. I waited for a step made towards me and I decided to go inside and he couldn't stop me any more and then I had the freedom to shoot."
"If you look just in terms of the injury, it's a big moment because it's a long sprint and you need to be explosive. In general I was pretty free in this game, but I also know that I'm not yet at my top level," said Robben.
"It was a very difficult match, we didn't play our best match today but in the end it's about winning. Hopefully, we will save our best match for when it is needed.
"It was a great experience to be on the pitch again from the first minute and to be decisive for the team, it's a great feeling," he added.
"For me there is no difference as my tasks are the same but everyone knows how dangerous Arjen can be coming from the right flank," he told Reuters.
"And if you see how he fills it in, that is amazing."
