Arsène Wenger believes Arsenal need to rediscover their defensive confidence after conceding four goals in Saturday’s defeat at Blackburn Rovers.

A new-look back four that included full debutant Andre Santos and recent signing Per Mertesacker succumbed to three second-half strikes at Ewood Park and the manager admits that defensive improvement needs to be made.

Arsenal have conceded 14 goals in their opening five Premier League matches but Wenger is confident his players have the quality to put things right, starting with Tuesday’s visit of Shrewsbury Town in the Carling Cup.

“You could see that the confidence in our defenders has gone a little bit and it is important to get it back,” he said.

“It is important that we get our confidence back quickly. We made mistakes and, at this level, you cannot make the mistakes that we made.

“We were guilty [because] we made basic errors. But now you just have to focus on the next game."
