Arsène Wenger admits his new-look defence needs time to develop into an effective unit.
Arsenal have been relatively watertight in Europe, conceding just twice in three Champions League matches. But they have leaked 14 goals in five Premier League fixtures, including 12 in their last two away games at Manchester United and Blackburn.
Wenger fielded two new signings in his back four at Ewood Park on Saturday - Per Mertesacker and Andre Santos - and Arsenal's defence looked vulnerable to the counter-attack, especially in the second half. The manager expects to see an improvement soon.
“I believe there is a little question of time and timing," he told Arsenal.com.
“A lack of concentration, a lack of communication, a lack of coordination and individual urgency [is behind the goals we have conceded].
"When you score an own goal, you have to look at yourself. It is never completely out of your reach where you have no chance at all. All the rest, you have to look at yourself.”
