How much longer would you give KP Paul...............
I'm not writing off Morgan's test career, but he needs to go away and work on his technique.
But he doesn't have one to play at Test level. He got into the team by playing innings for the One day side where he played some unorthadox shots and proved he had a good eye when in form. To be a Test Cricketer you need more. But the must for any top 6 batsman is to have a solid technique so when you are not in form or on a tricky wicket you've something to fall back on.
Pietersen is going to be one of those players who just won't get scores in the subcontinent - he doesn't like spin, likes to take the ball on the up and the ball coming on to the bat in front of big crowds - none of which you'll find much of over there. Get him playing infront of a packed house against either Australia or South Africa and he'll be fine.
