All this talk of him going is ridiculous really.
It's 7 months 'til he needs to captain again, plenty of time for him to re-energise and more importantly, plenty of time for him, Farbs and Trev to sit down, talk through his performance in India and areas where he is struggling with the role of captain and put it right - all t needs is a bit of common sense.
I don't see any stunning candidate to take over from him, and whilst I am not a 100% fan of his rather defensive captaincy, handing over everything to the likes of Root / Stokes / Butler will be the ruin of them in the way it was with Botham, Gower etc.
Sometimes you have to tweak waht you already have.
