If Victoria Beckham had known the quality of bandage available to patch up wounds, there is no doubt that David, following his run-in with Sir Alex, would have been sporting the latest in gauze technology. US scientists have come up with a gauze that acts just like a scab and biodegrades as the wound beneath heals.
