Arsenal boss Arsene Wenger insists he doesn't need to hire a defensive coach to fix their problems.

Wenger was in defiant mood after their Carling Cup win over Shrewsbury.

Asked if he should consider bringing in a defensive expert - such as former player Martin Keown - to help shore up the backline, the Arsenal manager responded: "I have just completed 30 years of coaching. I don't want to answer this kind of question."
