"It was a good result for us, we can be satisfied because we got an away goal," said the Dutchman.
"After the goal from Arsenal I thought it would be difficult to get the equaliser but it came very soon. We had to work very hard, and maybe we had a little bit of luck with some of their chances.
"It was unbelievable when Bendtner kept the ball out but you know when you play Arsenal away that it is going to be difficult. They can play beautiful football.
"I know a lot of people want Arsenal to go through because I hear people say they play better football, but we will see after the second leg and the best team will go through.
"Arsenal have problems in defence and some other things. They play very good and are maybe one of the best sides in Europe but they have problems with direct football and set pieces.
"We can stop them scoring at Anfield. I think it will be a different game there. I am looking forward to it. I was not satisfied with my own performance against Arsenal and I had to defend a lot. I hope it will be a different game for me as well on Tuesday."
