Former Arsenal star Stewart Robson has told Arsene Wenger to hand Steve Bould more coaching responsibility to tighten up the Gunners rear guard.
Just as Wenger had a £12million bid for midfielder Yohan Cabaye rejected by Newcastle, Robson urged him to address his backline frailties.
Wenger has been roundly criticised by frustrated fans after a shock 3-1 defeat at home to Aston Villa on Saturday.
The defeat came after the Frenchman had failed to spend a single penny of his transfer war chest on a significant signing this summer.
Now Robson has warned the manager that his old club face a ninth season without silverware unless his No.2 becomes more involved in defensive drills.
He said: “I don’t think Bould does enough coaching. Without even seeing the game I could have told you how the goals against Aston Villa would have come about.
“No great side, no side that wins the title, can’t defend. You have to have a good defensive structure and you have to have a good attacking structure if you want to win the league, if you want to win titles, if you want to win the Champions League. Arsenal haven’t got that.
“Yes, they are good when they have got the ball, they have got some excellent players, but when they haven’t got the ball and it changes hands, Arsenal are not a particularly good side.
“Until Arsene Wenger sorts that out and lets Steve Bould take some coaching and have the responsibility for the defensive side of the game, Arsenal will keep losing games they should win.”
