West Ham boss Alan Curbishley has revealed Freddie Ljungberg is their secret weapon ahead of today's derby against Arsenal.

Curbishley said: "Arsene Wenger didn't want to let Freddie go, but Freddie wanted a new challenge. We've had a chat with him about one or two things, we're aware of some of the things we might try and about what Arsenal like to do.

"But we need a passionate start and see where it takes us."
