Stewart Robson told Sports Bar that he feels that Arsenal are often exposed when a match becomes tactical.
He believes that once opponents identify weaknesses they are able to cause the Gunners significant problems.
Robson told talkSPORT that the team are not getting better because of manager Arsene Wenger but because they are doing their own thing.
The former Arsenal midfielder also does not understand why Liam Brady left the club after being involved with the academy.
Robson believes Brady left because youngsters were not given a chance to progress into the first team.
