The problem for Arsenal isnt so much the physical aproach it is well organised sides playing with two banks of four such as Villa on the opening day of the season that Arsenal fail to break down. When they play at their very best they will beat sides like that but if they arent at a very high level their style of play means that they do not come away with the result. The lack of a plan B in these sort of matches is still a problem for Arsenal and I dont see them beating Chelsea for the title.
