Arsenal manager Arsene Wenger has revealed that he is expecting Sunderland to be difficult to break down at the Emirates Stadium on Saturday afternoon.

The Gunners have failed to record victory over West Bromwich Albion and Norwich City in their previous two league games, and Wenger has said that he is anticipating another difficult contest when the Black Cats make the trip to North London.

The Frenchman told reporters: "Against West Brom and Norwich, we had about 70% possession but in the two games together, we have four shots against us and concede three goals.

"Tomorrow we face a team who is well organised, has a strong defensive system, and has confidence in their system as well."

Sunderland have kept clean sheets in their last two matches, while the corresponding fixture last season ended in a goalless draw.
