"We were the better team of the two. Arsenal only threatened on the counter attack. We are not happy with the draw. We could have got more from this game," Afellay told Goal.com.
"We practically gifted Arsenal two goals. The first one in particular was very unfortunate. The 2-1 was important for Klaas-Jan and for us. The positive thing from this game is that we remain first in our group. We still want to be playing in the Champions League after the winter break."
