The Dutchman had a few chances in the second half at the Santiago Bernabeu but was unable to breach Diego Lopez's goal with one attempt cleared off the line by Xabi Alonso and another hitting the woodwork.
"I had three (opportunities) in the second half, especially one where I hit the bar. It was a big chance and I should have put it in. With a bit of luck it could have gone in," he told Sky Sports 2.
"Then in the dying seconds the keeper (Diego Lopez) made a great save. I was counting on that one going in."
