I think Cook will get the rest of this series to prove himself, seems they really want him in the team.
Tough one this - Cook was our best batsman in Bangladesh - has a few bad days and people are calling for his head - having said that, in Bangaladesh opening is definitely the best place to bat.
Carberry is the next man in as a potential opener - and is in form, so he may get another go. The question is: do the selectors think he is going to come good? Cook has made a habit of being an "all or nothing player" he either gets out cheaply or gets in and makes a biggy.
The fact is when Cook goes back to Essex he always gets a mountain of runs (except for the start of this season interestingly.)
Personally I would stick with him, but if Bell was around, I would have him open the batting instead. As mentioned elsewhere, I am not a fan of moving Trott up to open - and I also think Cook will do well in Aus. Tough on Carberry - maybe, but I have this feeling that he is a journeyman pro who is having a decent run, rather than a true star in the making.
