This 5-0 drubbing will be much worse than the one England suffered in 2006/07.
Will be interesting to see the next series for both sides. SA should beat Australia but I think that will be a closer series than some people expect, especially if Johnson continues in this form. However, Steyn & Philander will be more ruthless with the Aussie batting line-up than the English bowlers have been.
Not sure who England have next, but they have quite a few decisions to make. I doubt Flower will stay, Cook should go too as captain but there's no real alternative unless they want to go back to KP. England need to settle on an opener and get Root back into the middle-order and keep him there. Also, they need to decide who their spinner and WK are going to be and whether any of the tall bowlers are good enough for Test cricket.
