Arsenal boss Arsene Wenger has hinted they will throw caution out the window when they go to Barcelona this week.

The Gunners must win at the Nou Camp to reach the Champions League semifinals after last week's first-leg finished 2-2 in London.

Following victory over Wolves, Wenger said: "I don't deny it will be a difficult task. We have to raise above the impression Barcelona left on us in the first part of the match, to have a game plan and stick to it. I believe we have to be audacious and not hide. I do not deny in the first part of the game that Barcelona were over-dominant, but if you look at the chances we created, we had some good ones."
