Abou Diaby knows he was wrong to lose his temper at Newcastle last weekend.

The French midfielder saw red at St. James’ Park after reacting to a strong challenge from Joey Barton by shoving the midfielder to the ground.

Diaby’s dismissal precipitated a dismal second half for Arsenal as Newcastle fought back from a four-goal deficit to snatch a 4-4 draw.

Arsène Wenger understands why Diaby reacted as he did but he insists that his compatriot must not make the same mistake again.

“Diaby’s was a response to what has happened to him in the past,” explained Wenger.

“I must say he had got a few tackles that he remembers and that is why he responded in a way he should not have done. I don’t agree at all with that but you can understand why he responded like that.

“I spoke to him about that straight after he came back home and he understands that. He is a very intelligent boy, Diaby.”
