A. Gambhir- Sehwag are not only the best Indian but also the world’s best opening pair at the moment. They are the best simply because they have been successful in all forms of cricket say Tests, ODIs and T20. The story so far for Gambhir and Sehwag has been terrific, but how long they can carry the same tempo for the next few years is the real test. Infact the pair of sehwag and gambhir has just started and we can not compare them with Sachin & Ganguly who played tonnes of cricket. Sachin - Ganguly are the great opening pairs in the One-Dayers. But Gambhir-Sehwag pair has excelled in all formats and already being considered as one of the best pairs in the world cricket as well. Gambhir and Sehwag, though, the story is not just the number of runs they score; it's the rate they score them at. Both are attacking batsmen capable of piercing the field on both sides of the wicket and going over the top, but they are also equally adept at tapping the ball into the gaps or short of fielders and running the quick singles. When Sehwag bats with Gambhir, the emphasis is much more on rotating the strike and getting the singles. The main advantages of this pair are their stroke play, Sehwag’s explosiveness, Gambhir’s maturity. On the other hand Sachin-Ganguly together have amassed 6000+ runs with 100 runs partnership 20 times in ODI. Moreover they also share a unique record partnership of 200+ runs 3 times. I feel Tendulkar & Ganguly is the best opening pair in ODI, because teams like Australian have always been a good team with good batsmen to follow so no pressure on their opening pair. But the pressure was great on Tendulkar & Ganguly where everybody in the middle order was not so consistently reliable. Tendulkar/ Ganguly had the class and the ability to stay in the crease and dominate the bowling. The record for the maximum runs scored by the opening pair is still held by Ganguly and Tendulkar. The 20 century partnerships that they have put up together, still remains an unbroken world record. Tendulkar / Ganguly by far because not only the world record for the best opening no of centuries and run in the world, when they gave india a early start India won 90% of their matches. The strength of Sachin-Sourav as an opening pair is that they are brilliant stroke makers; their ability to play for each other that was one of the most important principles of playing as a pair. Their special ability to hit even the good deliveries for boundaries makes them a daunting prospect for the opposition. Both Sachin and Saurav have the gift of timing and when in full flow both are elegance personified. Shots flow from their bats like sweet music and even the best bowlers can only watch and admire. When in the mood, the two can be as destructive as dynamite with shots like bullets racing to the boundary at the rate of knots. It is this special ability to blend Elegance with brute force that makes this pair the hub of fans and experts the world over. At this juncture I would say that Sehwag and Gambhir are doing very well at the moment. Statistical point of view Sehwag and Gambhir have to do lot more work. In my opinion, No doubt Sehwag-Gambhir pair is the most deadliest opening pair in the world today in all formats. But we can not say and compare that this is better than Sachin-Ganguly who has a very strong record in ODI. Sehwag and Gambhir are young and fresh but they need a lot to prove themselves especially away and until they do so, we can just say that this is a very good pair that shapes up the future of indian cricket, but still long way to go to judge better or the best among different pairs.
