Arsenal boss Arsene Wenger insists they can beat Chelsea this weekend.

Wenger has failed to win in 12 games against Jose Mourinho across the Portuguese coach's two spells at Stamford Bridge, drawing five and losing seven of their clashes.

"I think we have not always lost in 12 attempts. We have been close," Wenger said. "Having said that, the result on Sunday will just be down to the performance on the day. We are on a good run and we have an opportunity at home to beat them and we want to take it.

"We have a good run of form and good belief and solidarity. We have passed many tests recently when we were questioned. We have another test on Sunday that we want to pass.

"Chelsea's strengths are they have been very efficient on counter attacks and set-pieces as well. We have to nullify their strengths."
