It is a concern, as captain he has done well for us and he is a major player. We have always had this worry that in the future he might not be fit.
He's got a very, very difficult job here. He's an all-rounder - he's got to bowl, bat and captain the side.
We need Michael back as captain as well as a player. He is a very successful captain and very inspirational.
If Michael is not available, Andrew will captain the side.
