"Last year I got 24 goals and over 20 assists. For me it is normal to have assists. It is unusual I have had to wait until this week for my first one. I hope more will follow," said the Dutch international.
"I hope to do the same thing here in England - to score goals but also provide some nice assists. That would be great, but the most important thing is winning.
"It was 1-0 on Saturday, a clean sheet which was our third in a row, so it's getting better and better. That gives you more confidence.
"Okay I didn't score on Saturday, but I got an assist and maybe next week it will be a goal and not an assist.
"I can enjoy a really good assist. Saturday was a good assist, but the one against PSV - the first one - was really great and gives you a good feeling.
"But always the most important thing is winning and it doesn't matter who makes or who scores the goals."
