the key with arsenal is MOVEMENT. henry, bergkamp, pires, reyes are constantly changing positions. they don't really play with an out and out striker. they can constantly play the ball down the channels for the likes of henry to run onto.
on the other hand i don't see us getting behind the back of defences and making them turn. everything we do is infront of the defence. this is generally caused by a lack of width as kewell tends to wander all over the place.
