Arsenal goalkeeper Wojciech Szczesny is convinced new assistant manager Steve Bould will make them stronger at the back.
Szczesny worked with Bould while he learned his trade in the Arsenal academy and he remains a big admirer of the man who won three league titles during a glittering playing career.
"We've done a lot of [defensive] shape work in training, work on when we lose the ball and a lot of defending on crosses," explained Szczesny to arsenal.com.
"It's all very sharp as well. Steve likes to shout at players and keep them on their toes - so it's looking positive.
"I don't think we can concede more goals than we did last year," added Szczesny. "I was the one in goal, I was the one who conceded all those goals, and I'm just disappointed because it shows our defending was a big problem for us last season.
"We'll do everything we can to make it better."
