Arsenal boss Arsene Wenger hailed his side for a great attacking display in their 6-2 demolition of Blackburn at Emirates on Sunday.The Frenchman loved the way his players enjoyed themselves when going forward but conceded they must improve defensively."When we are confident we have a flow that looks like the goals will come at any moment and from anywhere," said the Arsenal manager."They enjoy what they do. They enjoy to play together and that for me is most important."There is some strength coming out of this team, we have to add some discipline defensively."We looked always like we would score goals."It's difficult to have so many people going forward and as well have everybody straight away defending well."It's a consequence of our philosophy a little bit."
