The following confrontations may make for interesting viewing:

1. Anil Kumble bowling to Sachin Tendulkar
2. Shane Warne bowling to Adam Gilchrist
3. Muralitharan bowling to Jayasuriya
4. Harbhajan Singh bowling to Yuvraj Singh
5. Brett Lee bowling to Andrew Symonds
6. Shaun Pollock bowling to Herschelle Gibbs

I am sure there would be many more similar interesting little battles to watch out for.
