We have absolutely no defence. It's just not there. Players are turning up with the relevant numbers on their shirts. They are standing in the correct positions at kick-off. But after that, they don't have the first clue what they should be doing. Wenger toiled for years to produce this. Even if we could pick any manager in the world and they would magically agree to come here, it would take them painstaking years to undo what Wenger has achieved.
