He can do some fine job in both department, he's arguably one of the finest fielder in the world and if dare to say then only Jonty Rhodes come close to him.
CSK needs serious introspection and they need to take some tough decisions. Deadweight needs to be removed and I would be happy if they start with Kedar Jadhav. Irrespective of the experience and closeness to the top people, non-performing players needs to be kicked out and young blood needs to be brought in. I am not sure about Suresh Raina. It looks to me that the relationship between him and CSK management is permanently ruined. In that case, he may be moving to another franchise, and it is going to be a big loss for the CSK.
