The secret of Alastair Cook's new fielding prowess

There have been a few theories floated about why Ali Cook has suddenly discovered a talent for spectacular catches after spending much of his young career having hands like feet.  Vic Marks in the Guardian has ventured the argument that he is simply happier fielding at gully; and a bloke in the pub last night reasoned that he might have changed to a better pair of sunglasses.

However, they are both wrong, as the reason for such a dramatic turnaround of skill is more fundamental.  Peter Moores has long been a coach at the bleeding edge of technology and innovation and it from this arena that he has transformed Cook - literally.  The Googly has discovered that the real Ali Cook has been replaced by AliCookatron 2.0, an android, for the purposes of fielding. 

After his wicket is taken, Cook is whisked away to his hotel room where he watches England field, complete with his bionic replacement in the Gully.  Nobody has noticed so far due to Cook's generally robotic demeamour.
