Chelsea, clearly bored with not being allowed to register new players for 18-months, have launched a clever viral campaign called ‘be the 12th man' in which you the fan take the role of a new Chelsea FC player... and it features some of the worst acting you're ever likely to witness.
It's been noted by some (wrongly) that Chelsea will struggle due to an ageing squad and their 18-month transfer ban. However, if any of Chelsea's more experienced players, especially Michael Ballack, are considering an acting career after they hang up their boots they should think again.
But then again - if Vinny Jones can become a Hollywood star...

The campaign is pretty cool, but doesn't make a whole lot of sense - you get stopped at security, it appears none of your new teammates have the faintest idea who you are and although Chelsea have got up to some pretty tricksy business in recent years I can't recall them ever trying to field 12 players at one time.
Anyway, try it for yourself...
