Not sure why you keep posting Piers Morgan's opinions as if they mean more than those of a random individual rather than far less.
No matter who would be the "best captain", to think it's an even halfway decent idea that Arteta should go to this group of players who seem to be doing great together and tell them "I know we voted for this season's captain, but I've changed my mind" is hilarious.
I don't see any potential positive effects from changing the captain other than shutting up the "pashun and desire" crowd. Rice can do everything he does without the armband.
