"This was a great result and there was only one team that deserved to win. We were good in attack but we were fabulous in defence. We didn't give them one chance all game, we were defensively very strong," said the Dutch striker.
"It was the perfect day for us. We controlled the game, we worked for each other as a team, and that was the big difference between us and them.
"It was crucial that we scored the first goal. I can remember when we played Chelsea earlier in the season at Stamford Bridge, I had a chance but put it against the bar."
