Choose the 5 whose performance in this series matters the most to you.
Ganguly (he'll have to perform to stay in the team, might as well start here)
Tendulkar (long-awaited return, praying that he can get into his groove quickly)
Raina (talent who might pose a danger to Gangs, Yuvraj, Kaif, Laxman in the ODI squad)
Dhoni/Karthik (both established in their respective arenas, but let's see how they perform)
VRV Singh (fast bowling prospect who could, along with guys like RP Singh, make his mark quickly and challenge Agarkar, Zaheer, Nehra, Balaji)
