Arsène Wenger says the Club are looking to sign a midfielder and a defender before the transfer window closes next week.

Arsenal announced on Saturday that terms have been agreed for Alex Song to join Barcelona, and the 24-year-old is expected to complete his move to to the Nou Camp soon.

Although Wenger is confident his side have the resources to cope with the Cameroon international's departure, he still hopes to add to his squad.

"We are looking to bring one more midfielder in of course, and maybe one defender as well because we still feel we are short in some positions," he told Arsenal Player.

Wenger admitted he was "frustrated" by his side's failure to beat Sunderland on Saturday, and hopes to see an improvement when they travel to Stoke this weekend.

"We didn't lose, but it is frustrating when you are home with everyone here and you do not create more chances than we did," he said. "It is very difficult to understand."
