The Sun says free agent Becks has agreed a top-secret plan with the Gunners to train with the first-team squad while he ponders his next move.
The former England superstar, 37, is reporting for duty at Arsenal's state-of-the-art Hertfordshire training HQ this morning determined to prove he can still play at the highest level.
An Arsenal insider said: "Beckham wanted this all kept hush-hush. You have to wonder why?"
Beckham has no ties after ending his five-year stint in California.
