Manchester United boss Sir Alex Ferguson says they're still keen to land new signings this summer.

Ferguson updated the transfer situation during a press conference in Shanghai.

"We've been trying all summer to add to our squad," he said. "We've got Kagawa and Powell and we're working on one or two other things. I have nothing to tell you in terms of confirmation as to whether any other players are joining us at this moment in time. But we are trying to add to our squad."
