I think it's very important that Cook learns about being more ruthless.
Trott in that scenario is perfect, all he needs to do is be a bit more dominant when we're setting a total and he'd be perfect. One of the most pleasing things(other than winning!) was Buttler's work behind the stumps. If he can build on that, he can be a great keeper.
Interesting KP named in 20/20 squad against NZ.
