Arsenal boss Arsene Wenger says they won't be taking lightly Champions League opponents Villarreal.

"It is maybe a good opportunity to play the first game away from home, but at that level it is very difficult to be creative in your statement," he said.

"It will depend on the quality of your performance and the players available as well.

"We have learned that to knock any Spanish team out is very difficult.

"There are many big clubs in Europe who are not in the quarter-finals. We are one of the five clubs who have for 10 consecutive years qualified for the Champions League, so to go to the end of it is our immense desire."
